Think it could use a brightness/contrast layer? I think it does... Looked a tad better on the bright bg of photoshop xD .... or maybe a sharpen... I'm not sure :/ c&c ? edit:
Im Lovin the effects but the lighting seems to far on his helment by like 2 inches. Makes the lightning seem overdone. The text doesnt work there. Try to move it somewhere else like more mid top left.
Everything is good, but just fix the fire on the right , it seems like it's standin out a little bit too much.
