Hey, the pic looks really good, actually.^_^ One thing is, if you are trying to add a lot of shading and detail with your colors...maybe try doing the lightest color first and adding darker and darker until you get it right, that way you can go over stuff rather than just mess it up. Just sort of a safeguard that might make them look better. The horse looks great, I love horses with this sort of color. Anyways, great job, hope that might help a bit. Good luck!!

Your horse is lovely, and the color is good !!!!! If you want to improve it, you should add some darker colors on the body, like you have done in the mane. :)
