Ya know, it doesn't actually look half bad, though a couple of things need fixing.

When it comes to the hair, I'd suggest making the outline less detailed, cause the way you made it now it looks all jagged and kinda sloppy. As for the shading, you got the amount of colors right, but the shading style is somewhat off, and it ends up looking a bit pillowshaded (in my opinion, at least).
The palette seems fine to me but then I'm not much of an expert at saturated palettes, so you'll have to wait for 1up to tell you if it's ok. I did however notice that you have two colors that are almost exactly the same. The darkest shade of green. You have one color on the hair and one on the shirt. Then again maybe that was intentional?
Now one last thing I noticed, as with many other sprites in this thread, your character seems to have developed a bit of an air hump. I'd suggest straightening out his left (our right) leg a bit.

(This ended up being a lot longer than I thought it'd be, haha)
