I like how it is green (I'm talking about the back color, of course).
xD Nah seriously, I like the clothes you gave him, and the sheet is well done even for such a simple edit. The blur on the portrait could be removed though. And I see you used a rotate tool on one of the damage sprites, you should have redone it manually. And it should have an animated stance too. IMO 7/10, keep up the good work and you'll get better and better.
