I can give you a small tip. I've personally never drawn a sheep before but if we have a run down of the anatomy of one real quick, it might help?
Alright, so here we have our sheep. Take note how the legs bend, the front bending similarly to our legs, and the back bending back, like an elbow.
They also have large, rounded stomachs and a broad chest (kind of? it looks like it at least). Also take note of their hooves! the front are a bit more "open" and the back a bit more closed.
As you can see, their faces have a very long and thin muzzle, and their eyes situated more towards the top of the head and further apart. Same goes for their ears, which actually end in more of a point than rounded!
I'm sure someone else could help out better than my explanation, but maybe going over that could help you figure out how to improve?
Anyways, this sheep you drew here is very cute in my opinion, and I think you'll improve the more you draw! Good luck!
