very nice indeed. colors well-fit. resolution good.
i may be mistaken but there seems to be a transition from polygonic to smooter as the human figure become more detached from the branch? the faces on the top seems smoother. i though you may emphasize that more only if that was the intended?
also, i was thinking that the main item is like a branch of a tree. so, instead of having just trees, leaves in the background, you may have replicas of the front branch. like a forest of trees growing human within. you may put leaves at the very far. just an idea.
