Lighting's from wrong side of the top, the focal point placement isn't very nice (it would be better if you stuck to rule of thirds), and the text on the right doesn't go as it is, blur it, or take attention off it somehow.
Also, get rid of that border.
put it right until the bit in between the face and the gun muzzle is on the power spot place.
Also, look at the lighting on the gun, and then where you put the lighting - it's at the wrong place >_<
