Wudotree... i'm not a fan of this sprite of yours... the spots on it's belly have to dark of an outline, at least the middle one and far right ones do... tone it down.
The outline is too dark... too black... around the spots...
Also, the arms make little sense, unless they are supposed to be dispropotioned like that... (his) left arm needs to be bigger to match with his raised arm...
raised arm is way bigger than the other one... make them more the same size...
As for the top... it is extremely awkward... the black outlines detract from the sprite, but in general, this part doesn't look so good. I think it's the way the trees expand outward from the base... but still, his head looks like it has a funnel on the top...
black outline = BAD... you don't need all that black, you can make it lighter to match the light brown spots...
You have a very nice concept, but it still needs some working on...
It's a great idea, just keep working on it...
Don't give up...
self explanatory...
Keep Spriting
