Anything i can add to make it pop at all? Suggest anything you think would be Cute/Awesome/Amazing!

This piece is quite cute! I really like the concept and I love the contrasting colors of the horses' stock. It definitely makes each one stand out from the background.

Although, I do have a few critiques that I feel could help your art a lot.

First of all, it appears that you simply cut the horses out and pasted them onto a background. I would recommend looking up some horse prep tutorials on DeviantArt or see if there are any available on here in the forums. I feel that horse prep could help your work a lot.

Second, the horses don't look like they belong in the background. I would definitely work on highlights and shadows. In this piece, it appears the light source is coming from the top left hand corner. Parts of the horse facing this direction would be lighter than the sides not in the direct light. The stock images you chose don't have the same light source as the background. Working with highlights and shadows would fix this. :) Also, I'm not sure what program you are using but try to mess around with some of the Auto-Color, Auto-Contrast, and Auto-White Balance features. When I was starting out with art, these helped me make my horse seem as though it is really in the background.

Third, the manes and tails are really awkward and unnatural looking. They seem blocky and do not flow. When working with manes and tails really try out different tools and brushed. And definitely watch or view some tutorials! Tutorials as well as studying natural horse manes help a ton! Manes aren't blocky so be sure to make some fly aways and strands of different lengths.

I hope this helps! Please mail me if you have any questions or if you would like any future tips! :)

Thanks!
