looks like you're better animating than spriting. Sure it's important, but even good animations get worse if your shading/outlining skills are poor (having excellent spriting skills and horrid animation skills, too). The tip is... try balancing these skills until you have both good spriting and animating skills.

Since the animation looks alright, I'll comment about the sprite itself. Increase contrast in the shades (make the shading more noticeable) and use less colors. You know, 1000 different colors =/= good sprite. Choosing your colors wisely is important. Use some inner anti-aliasing to make it smoother. Try removing the black outline and shade it, it'll look better if well done. Check some official sprites to see those techniques in action.

You have potential, so continue trying
