That's a really nice style you have there.

But there are three things I'm not too convinced about. The prop rocks have very strange shadows (especially the one at the bottom right on the first image). The river mud thing looks very strange as it doesn't effect the terrain at all. Maybe adding some clouds and what not would be cool, maybe even some mountains in the Sky box because it feels a bit empty.

But over all I really like this!
