The hands could do with a bit of work (thumbs maybe?), and there are quite a few polies on the head and shoulder that could be removed (around the curve(S) at the top - lots of small polygons), but the texture is pretty nice and the shape is good as well. I think with all the detail you have on the texture things might get lost at a distance, since there isn't much contrast between... anything and all the colours will blur together to make a greeny brown blob.
