Nice work, some great shading in this picture and apart from the slightly skinny arms the character is pretty well drawn. Great tree too.
The one criticism I would have is the feeling of depth in the picture - there's not a great deal of it.
The shadows seem to go off in different directions (guy's shadow heads over the tree towards the top left but everything else seems to go to the bottom left) and there's not much obvious change in the terrain behind him.
I think a few rocks, a few blades of grass and a couple of carefully chosen shadows could improve it.

Nice work overall though.
