Here's some visual goodness.

You should get your colors from the HKCP thread:
Here
They have palettes specifically for clothes and hair. (Sorry there's no light pink)
The Sprites are viewed from a higher angle so the skirt should curve around the legs and not have such a straight edge; same for the belt. Try not to blend the colors from darkest to lightest, it can look "pillow shaded" which is a no-no. The lightest pixel can touch the darkest pixel without any colors in-between. Practice.
As for the hair: If she's going to have her hair pulled to the side in a pig tail then her hair should look pulled tight. And the only left over might be the bangs in front. On the other side her hair should contort with the shape of the head. The only time I say other wise would be if it was longer hair. There was also that white empty spot between the hair and her face that shows she has no hair back there. Oh, and like I said before the top is flat.
