I'd do away with the texturing on the tail as it's kinda gritty for a space so small. If the sprite was bigger, you could keep it.

also his head has straight lines (not saying it's wrong, but you could use a more organic shape) and his right arm goes forward a little too much, retract it by one or two pixels.

also outline his feet where they don't connect with the ground. Some styles ditch the sole's outlines so the ground tiles' outlines can make up for it. But if they aren't touching the ground, there's no reason to leave them not outlined.
