Flying Horse Castle

So I've been working on this for a couple days...at first I just wanted to do a picture with a castle in some clouds, but being the horse lover that I am, I figured no picture would be complete without a couple horses
So, many hours later...here it is! I think it's pretty good (except the white horses mane = bleh), but I am definitely open to comments! So let me know what you think!

EDIT 8/11/10: So I actually REALLY fixed the horse hair! And the wings a bit. I think it looks lots better

EDIT 7/20/09: I fixed the horse manes/tails a little bit...the old white horse mane/tail was driving me crazy, it looked so fake...Still not 100% happy, but I think this is an improvement.
