He lacks deltoids and triceps.
I dont know about anyone else, but raising your arms like that is increibly painful I think I was about to pull something when I stopped, I couldnt actualy assume that position. Have his arms go straight up like |.| that, where the period is his head.
His ribcage is too short. It ends that far up yes, but only right beneath the middle of the pectoralis, on the sides it extends down much further.
Hehe... I am honoured you actually put yourself in this position... but he is a tree and doesnt feel pain. I too put myself in this position ( a lot) but as I am double-jointed I didnt feel anything wrong with it
About the muscles... (deltoids and triceps) I am not that great at anatomy... but I'll add them in the next edit.
I didnt actually notice the bulge by the armpit, thanks for pointing it out.
Miascugh - part of the pallete is Henk Nieborgs... He is definitley one of my major influences. The gap in the middle is quite dark... But I was to go for more tree than human, with dark bits, like the tree was overwhleming his muscles. But like i said still very in progress, and when i come to texture the abs it will probably look better.
mcow - I really appreciate the edit and will take it all into account
Thanks for comments so far, Its probably a bit late to do more work tonight but I'll definitley get a big chunk done tomorow.
