Ya, jpeg=the Devil's test-tube baby.
Anyways.
Before you even work on explosions, make sure they're dull and blend in with the background. Anything too bright or flashing will detract from the main focus point of the piece. As for the guy, you need to redo the bottom of his hair. As I can tell, it's falling onto his shoulders, or it looks like it. This gives a very wrong view that his shoulders are HUGE. Either not let the hair fall out that far from the head, or add some more room at the bottom of the picture so you can clearly show it's not falling onto the shoulder. The head also seems a bit lopsided.
