Bump, c'mon anybody?

The smudge coming off of him messes up the flow.
The blend is done well.
The lighting could be improved by making light come from his gun.
Seems a bit empty.
A bit LQ with the smudge going on him in all different ways.

Thanks, the smudge that messes up the flow, is that on his bottom left side? also how would i make his gun the lightsource?
