My Fakemon and Other Pokemon Sprite Stuff

I feel like you should try something organic rather than a tree. Basic shading knowledge has to come before textures.

Also, does this have any kind of theme besides just being a tree? Pokemon usually have more thought put into them than that. It might help guide your design if you have something to follow. Try getting ideas from other pokemon, and check out what kind of shapes their bodies use.
Keep trying!
