sigh...i disagree with the people above me.

personally i feel that the lighting isn't really good at all. first it's a white soft brush which looks unnatural. then it's way too strong to where it overpowers the rest of the sig and doesn't work with the heavy shadows of the render.

as for the blending i think it's equally lacking. smudging the render so that it looks like part of the background kills you depth and looks weird to have someone randomly cut off at the chest.
