Noone likes to reply really.
Good concept going on there, I'm not liking the swirly bar thing next to his sword on the middle right, nor do I like the white circle, doesn't really fit in, but I understand why you did it. I like the other fx though.
The background is extremely dull however, similarly to your current sig, you need to remember these things: Background, background effects, render/stock, front effects. Make sigs with that reminder and you'll soon improve.
I'd suggest some finer smudging or at least clipping masks or something to liven the background up, but don't make it too messy otherwise you'll lose your focal.
