Oh, the color choices here rock.
Reminded me of some old game I had, a turbografx 16 one... Damnit, I can'tremember.
Nice work!
Though overall I kidnda like the piece, the trees do register more as a coil of ropes rather than trees.
Though I did recently see a weird tree with a similar coiling pattern..

I think if you want to keep the coiling pattern you should reduce the contrast between the lines, so that looks more solid.
I absolutely loved the colors. They could've been used better, but the shiny way everything looks is kinda cool.
