Gnarly! :D!

the one thing that's really apparent is that the right leg shouldn't be so straight; the fetlock/ankle right before the hoof should be angled downwards more, esp. for the angle the body is at, like this (i know it's a horse, google is giving me a hard time lmao). the other leg could probably use some tightening up on the knee + a slightly less severe downward angle. it's back is probably bent a little bit too upwards as well, most hoofed animals don't have very flexible backs.

BUT. it's still a really nice piece. you have a great eye for detail and that really makes a difference. it's still absolutely gorgeous.

This is a supremely awesome design.
I particularly like her wing-feets.
