So after coming up with the strange idea to make a rpg from a jump'n'run perspective I've started doing a little mockup for it.
The ground is made of 16*16 tiles while the tree is just one big sprite. It's a bit inspired by Helm's mockup from the video-thread.

I would really like to have some c+c on the trunk, especially shading-wise, since I think it looks pretty flat. All other critique is appreciated aswell. I came to learn

(The thing in the background is supposed to be light shining through a tree, which will be most likely removed as soon as I have a better idea for a background.)
