Looks cute Hanzo :D Idk about the back ground style choice, I don't think it fits that well :\ perhaps it's the taste issue, but the matalic should be more like a cloud or something softer, it just clashes and doesn't make as cute as it's shape.
and n/p about the pricing, I was just guessing in comparison to spriting commissions, when people commish me, it's usually 10$ per rtp sheet, and thats about 2 hours of work, logo's should cost more though as their just in less demand per game (one, lol) and their worth more XD plus, theres a hell of alot more spriters than logo makers, lol.
