9/10 Looks great, better than anything I could do. :P
Although, the beam thing coming out of Megaman's arm cannon thing could use more of a 'splosion where it comes out.
I dont like it. Background is to flat. It holds no depth at all. The sprite is pixalated and the rest isnt (aint compensated). Ad the beam needs a splash. Also try some smudging for the background.
actually it isn't. The point of a sprite sig is to improve the flow of the sprite. If its pixelated make the flow pixelated. Some prites arn't pixealted at all Since this one is it needs certain ammount of pixelation on the rest of the renders.
Make a V2 with a little pixaelation on all renders exept the render layer.
