Rainbow Dash Test Sprite

I was originally going to try for a completely different sort of sprite with black outlines and different shading styles, but decided on a Sonic The Hedgehog 3 (And other sonic Genesis titles) inspired sprite. Like the pixel art I've been making over the past few days, this sprite was made completely from scratch and the rest of the sprites I make of the ponies will most definitely be the same.

Thoughts?Do you think the shading style works well here? Should the rest of my pony sprites be in this style?
I'd love some opinions, Guys.
