I saw an image on deviantart of a tree sometime last year, and after thinking about that and some tree designs on some Magic the Gathering cards I came up with a concept I'm really into, it just needs a lot of refinement.
I'm pretty happy with the trunks, eh on the roots, but I'm looking for a lot of feedback on the top half.

Thanks guys!

I'm hoping to get this if I like the final outcome. ...after a lot of editing, of course.
