Thanks! The concept actually was to introduce 3 different "layers" on the tree monster: body with barks, head and especially the forehead with "younger", smoother branches, and of course the hairdo with them curly clusters. And the biggest challenge for me was to have as many details as possible, without making the overall picture too busy. Hopefully I've succeeded. 

I think it's great. Love the tight cluster placement. It really helps with the bark texture.

It's a shame the hairdo doesn't look a lot like leaves, because the rest is good! I like the bark's texture and the creature's face :)
