Zbush -> UV mapper -> Cinema 4d 7 w/body paint - Poser -> Cinema 4d for render - now I am making a walk loop.
I got the from a root clunp of an old tree, that tipped with roots sticking up. it had moss and on the lower side, and the root looked like spikes on its back
Looks great
Pretty neat looking. Reminds me of one of the creatures the Swamp Thing fought on one of his movies. You will have to post the animation when you finish. 
Another movie came to mind as well…it was one of the Puppet Masters series. Those marionettes fought some demonic type creatures that resembles the Treeman. Keep up the good work.
