Looks pretty good. The colors spice it up a little but it doesn't really flow with the main image. Also the trees in the back look out of place.
I really like it. Maybe not fully desaturate his face. That's all I can think of; unless you want to make the background colors a little more Opacity. But good job and good job making it have some depth,
I think the colors complement the stock well, but his body contrasts too much IMO. Maybe adjust the lighting so the face goes along better. Or do a white farmer. lol (I love black people fyi)
Okay, this is the last time I'm saying this. I've said it about almost every one of your sigs, so if you ignore it again I'll just shut up. Work on your text. You always just have it plain black and sitting on top. It never blends in and never goes with the flow of the sig. Try other things for once with it.
Dude I don't know if you relize but that sig battle meant nothing. There is no way in a million years I can pull of a sig that nice. You are very good with effecs that I can not make. You are very good with graphics, better than me that is.
