Lighting on the left is good, but the right needs some dodging. I like the effects around his body, but the gunfire stands out a little too much.
Get rid of the Red on Colour, you can barely see it. TUT PL0X I'd really like to see how you got this final effect, I've seen many people do it where it looks like yours, the BG like a Pastel Effect, I've always liked it but never have been able to do it.
