Ok i tried some tips from my other sprite and this is result: rate please and again say whats good and what could be better
very nice, but can hardley see text and looks too simple. maybe some more c4d with a layer style. 7/10
It's over saturated. Oversaturation hurts the eyes, and burns away most of the subtle detail in your sig. Also the light in the picture seems to come from where he's standing instead of from the explosion. I think it would make more sense if the c4d were centered at his hands.
