Very nice! You used a style of diognal shadowing! Nice! This is very good, especialy the top, but the bottom parts seem a little worst thain the top ones! Perhaps you should trie to recolour them with more relitive colours(ones that are not too diferent from eachother)and do a doover because it dose not make sence. But other thain that this rocks! 7.5/10

Did you use a reference? It's good practice in this site to post a link to any reference picture you used. 

Fairly nice for an early pixel.  Keep in mind that you should make blank backgrounds transparent unless it serves a purpose, which it doesn't in this case.  So make that background tranparent ;)
