Good, very cool wee guy if nothin' else, but you gotta work on the legs; they're too solid. Edit them more custom instead of just rotating the sprite. That may work on the moving animations, but for the death one he looks like a plastic toy knocked over.
And the scythe could be less curved and finish looking sharper.
On the plus side, i like the skill use ones and even just the sprite itself.
It needs work, but for a first sprite, good.
