Not a bad start at all. However, your palette is very unsaturated, that makes it too bright. I don't recoment using pure greys/whites/blacks on sprites, since they tend to look flat. Also, the hair could use a highlight.
The parts of the shading that are yours are pretty good (most of it seems to be recolored template, but it's only obvious on the boots). You've done a good job with the hair at just suggesting shape - too many people try to sprite every little detail at first. Kudos. ^_^
I'd check out Tana's tutorial, it has a section on both palettes and hair that are very, very good.
