Of course horse!
Actually I think you got the anatomy exactly right.
Damn good work...though just a thought, you might want to work with the Brony community on horse anatomy. Just saying they can be of more help than most of us out here. But really though, she does look the part.
I really like your style, it is basic horse anatomy, but its still pretty good.
The horse anatomy isn't too bad. I guess you could say it's a little too simple, but the rest is great!
