Option A and B looked great, option D looked okay with the colors. The one that looked like lungs was not very appealing to me

I like the text and the colors in A the most.

I like option A because I notice the "Numbers don't lie. But people do." on the top and that makes me curious about the book. The graphic and placement of of the words are better in option A compared to B. Option D cover is nice and would also make me curious about the book. Option C is okay.

I liked choice A since the cover is very lush and vibrant which draws my interest right away. I also liked how choice A flowed well together and was easy to look at the whole cover.

i like option A best b/c the chorus of colors is stunning and captures my attention the best. option B is much like option B for the reason why i like it. option D i liked least b/c it looked like some boring painting i've seen in a museum and that just turned me off

A is the most intriguing and mysterious and the colors separated enough to look independent. I'd look at it first. C is nice and obvious what it is however I'm used to seeing only one side colored to visualize the creative side, so this is unusual to see both sides in bright colors. Also it looks like the rainbow alphabet so I would assume it's about gay people and I'm not gay so likely wouldn't look twice at it. B is ok, if a bit jagged and again with the rainbow arrangement, wouldn't expect it to pertain to me. D looks too much like anime so I wouldn't expect it to contain serious information but more fluff stories.

The tag line is easily seen. The picture contains very bright and captivating colors. The design is extraordinary.

I ranked option A first because I think the subtitle "numbers don't lie but people do" is eye catching and is more appealing to be presented above the title "Cloudthinker." I ranked option B second because it also featured the subtitle, but it wasn't as prominent because it was featured below the title. I ranked option C third because it doesn't feature the subtitle, but I find the design of the cover to be unique and attention-grabbing. I ranked option D last because it neither featured the subtitle nor had a very unique cover design.

A seems electrifying interesting and catches my eye / B Colors catch my eye /C I don't really like the design / D makes it feel kid fantasy which I don't want

I liked A the best because the phrase "Numbers don't like but people do" would catch my attention. B also does this but it doesn't have the phrase front and center like A does.

C looks more like lungs than a brain, which doesn't fit the theme. C has the most eye-catching and appealing cover overall

I find these book covers to be the best looking overall

Option B looks quite intriguing. Only issue is that it could be mistaken for a movie poster.Option A is quite clean and attractive.Option C is good but looks a bit like a textbook.Option D is a touch too busy and distracting.

B feels incredibly ominous and interesting.

I liked the more abstract and thought provoking designs of the cover art in B and A, and I especially liked the orientation and form of the cloud-like parts of B.

i like the "numbers don't lie" in B and A

Only B and A contain the tagline, and I really like it. It's easier to read it in B though.

Option B. I would read the description based on the cover because the graphics and the wording is intriguing. However, it is really hard to make an accurate decision based on the cover without knowing the genre of the book. Is it reality, non fiction, fantasy etc ..?

Option B has a great design element to it. The image is really aligned with the numbers theme as it looks like cubes blending into chaos... it goes with the numbers don't lie idea. Option B is a thinking mans cover. It is vibrant and thought provoking.Option A is not quite as geometric, but it is very vibrant and is a real attention getting cover. You could stare at this cover for a long time as there appears to be hidden images in the design.Option C is a good looking cover, but it is really lost in all the bleakness of the white. It also lacks the "numbers don't lie...." addition that Option B and A had.Option D is too fantasy looking. IT looks like the girl is floating on top of a tree in the sky. It looks like the cover of a fantasy novel.Option B would get my attention and my interest. It is a thought provoking cover.

The wisps of smoke pattern that sort of merges together into what looks like a tree..it's odd and grabs my attention.

I ranked B and A higher because the 'numbers don't lie but people do' line catches my interest, and is in line with my worldview. Of the cover artwork itself, I do think I like B best - it's a little strange, a little uncomfortable, but it makes me want to know more about it too. C is a little too rainbow, and D looks like it might be a novel (if it is, go with D, but I don't think it is).

I ranked in the order that the covers would catch and hold my attention.

I find the brain to be very intriguing and would likely grab my attention.

C is the most unique, which I quite like. It draws my attntion. And the watercolor in D is the best because the art style is interesting and unique. A and B are really kind of solid, but also boring too

I like the rainbow brain on the white background. It could perhaps be improved by putting the tagline on the cover like it is on some of the other options.

I like all of these although for me the reason I picked the number 4 is only because it's a little more abstract. All of these are beautiful and have nice big bold colors. I really like the number one though because it also shows the idea of the brain thinking

i like c- its like a mashup of brain, lungs and geometry, the next is cool because it gives a feelin of the elements i assume will be discussed being boiled down, a is this pretty overall entanglement that is intriguing, d...doesnt really lend to what i assume the book will be discussing....it feels out of place like it belongs with something related to anime or young adults.

The artwork is amazing in Option D, but Option C's cloud and shapes forming the brain really fit the book title way more.

I think these are all really creative and I like them. D has the most on theme and whimsical cover. I like the looks of the others and they drew me in in my chosen order.

D by far is my favorite for the art style and the multiple different colors mixed into one. It gives off an ethereal feel that makes me highly interested. B and A are ok covers that sorta get my attention

D I feel has the prettiest cover to it that is able to make it stand out the most to me.

The cover on D is very intriguing, whereas C makes me uncomfortable.

I like d. The imagery fits the book title best.

The images of the rainbow clouds that are shown off in choices D and A have a cool aesthetic for a book cover.

D. looks like a fun adventure, beautiful futurescape and overall colors draw my attention. option A is okay but not quite as unique The rest are kind of plain and i would glance past.

I really like this cover. It seems like the girl is looking out over a beautiful lake and sunset. The variety of colors instead of normal make it seem more interesting

I prefer option D as the cover ties in with the title as the image has a more cloud like appearance.

I like the image of option D and the font of otion B. The image of A is too confusing and C just does not work as a brain.

It is more appealing to me. I like the lone girl image in colorful valley.

I love option D's book cover. It looks amazing like a dreamscape and I would definitely read this based on the cover

C is the least interesting, an image of a brain made of colored twisted wire suggested nothing to peak my interest. A is weird, really weird, even too weird with stringy gooey looking stuff attaching to a mass of colored live wires twisted and attached over the outline of a head and the suggestion of a shirt and shoulders is creepy. A and B both were good with the line Numbers ..... Do. B is mesmerizing with its almost fractal shroud between the sky and a hint at an island in the sky. I would be most likely to pick D up and read the details because the one figure looking for the small dark one personalized it and made me wonder who and what was the cloudthinker.

I love D. I don't know who the woman is or where it is she is situated but combined with the title of the book and the imagery, I would be very curious to find out what the story is about, what time period it is set in, etc. I like Option A next for the big, bold explosion of color. It makes me think of circuitry in the brain...and I would want to peek inside to see if that's at all where the story is headed. I like Option C next....but oddly, because it looks like a set of lungs. I am not sure of the connection between the floral colors and the shape combined with the title, so I might take a look. Lastly, I chose B....but that's only because of the vagueness of the shape. It doesn't really make me think of anything even when I look at the title with it. I like the colors but it doesn't make me curious like the others.

I prefer the option D fantasy book cover image because I like the colorful clouds and person shown in this option D book cover the most. I chose options A and B second and third because I like the more colorful swirls and pathways shown on the option A book cover more than the hanging threads with the weak color variations shown on the option B book cover design. I chose option C last because I do not really like the brain shaped threads and white background color on this option C book cover as much though I like the color selection used here.

Option D because the cover was the most eye catching and attractive

The colors in D look really interesting. I like how it’s like an alien landscape

I like the two covers without that tagline because I find the art more dreamy and aesthetically optimistic, plus they don't have the pessimistic tagline

D is by far the best, it is the most beautiful and pleasing to look at, all the others really just look like stock images

Could D catches my interesting the most, out of these 4. I'm very fond of surrealistic landscape-style artwork, so this one really speaks a lot to my persona; styles and interests. It'd definitely get me to look more into it.

I prefer option D because the vibrant colored clouds appear to be coming from the character on the cover, which is appropriate for the title.

I find the image on D to be intriguing and it's definitely the cover that would make me pick it up to learn more.
