Alright, you did really well c: horse anatomy is quite difficult
1. The neck isn't curved - it's rather straight and a little shorter.
2. The head could be a little smaller.
3. The body in general was too thin, don't be afraid to draw more muscles on a horse.
4. The legs were really well done, except the hind left one was a little off.
5. The hoof was well done as well. In my opinion, the edge was a little off too.

Well done, it's great c: Note that that's only how I draw horses.
