Nice tree. The only thing that seems a little out of place is the dithering.
I like where you were trying to go with this one. It has that tribal tiki / Legend of the Hidden Temple Vibe. There's really nothing negative to say about it. Good job.
Great design and interesting pattern ! Shading seems inconsistent in some places, and the dithered shape on the right just ruins the piece =/ you'd rather chose your darkest brown shade for the bg too.
Oh woah, beautiful style going on ^^
