Well done!
This is a very well-painted piece, but my only problem with it is the water. Is it frozen? If it's not, then you forgot to add reflections to it, and that's very important. And another thing about the water is the rock it's touching in the picture. It's obvious that the girl is highly elevated. but the rock right beside her blends with it as if it's connected which messes with the perspective.
Everything else looks nice and organic, with a nice feeling of depth. Gud job.
