I think the tree guy would look far more interesting if his face almost looked as if it was just stuck to a log, with roots popping up under his features and twigs/foliage popping out of his nose or something.

I agree with that, but I would think foliage hair would be cool, because remember, he's turning into a tree and the top could have branches with leaves on. I suggest you blend the skin and bark more, like an intermediate type of skin (half human half tree).
The "normal" guy's neck shadow is troubling me.
Apart from that, these are good works!
