V1. Move the stock over. There's way too much space that is capable of having more flow-giving effects. The colors also need some help. It's very monotone with grays, whites, blacks and reds. I'd either move your stock over or crop it to so the stock looks like it's somewhat-close to the middle (not literally in the middle). Work on depth too. I'd use blur/sharpen for that.
Move the stock over, and apply image (Control+Alt+Chift+E, or if in GIMP, Image>Apply Image) and make some of the effects be on him, for blending. And take the random white lne out. It does nothing for the sig. And don't put any brown, IMO.
