Vipershark sucks at spriting

[Vipershark]

Updated.


Ref: http://i38.photobucket.com/albums/e140/V...uruRef.png

Changes:
1. Got rid of the black outline.
2. Made her 2 pixels skinner.
3. Made her arms about 2ish pixels longer.
4. Gave her an actual neck.
5. Added a little shading to the bow on her chest and her legs.
6. Changed a few of the colors to fit closer to the ref.

So, again, I have no idea how to correctly shade hair. For that matter, I'm not sure how to shade the rest of her at all, as I suck at shading.
Also, I'm not really sure what else to do with the ribbon on her chest. If I try to make it any bigger, it obscures other stuff and ends up too big.

Crits needed, EDITS WELCOME.
