Well, if you are going to shade it, do not shade it like you did. The head shading may be specific, but it looks very messy. When I shade my sprites, I usually do 4 shades for each color as long as it is used a lot. (The darkest being the outlining.) The origin of light should be the top, I think. I think that sprite would look good with no shading, maybe no outline, kind of giving it an arcade/ old school/ gameboy look.
