I don't mind at all if you use my edit, but don't take it as the best this sprite can get. Listen to the others to see what they recommend, and work on making it better.
I was mostly showing you how to shade it in a more proper way, but the jacket was really hopeless as it was so I changed the palette a bit.
EDIT:
To answer that question;
Spriting is all about making the best out of limitations. Using an excess of shades makes it look gritty and busy. Also, having a whole bunch of shades often goes hand in hand with having low contrast, among other things.
