FHS!! lol you have a sever case of cloating head syndrome. Get rid of some of the effects at the bottom that way it doesn't look like his head is coming out of nowhere. I like the text you did a good job on that.

WHats with the compo? Smack in the middle liek that is just uninteresting. Move him over to the side it'd be much better.

WHy is it white around his head? Is it because you didn't bother to cut him out of the stock he was in? NOt good, i dislike the sloppyness. Pretty easy to tell what you did.

Overall the sig is okay but IMO looks like your half assing it.
