Did this in my spare time And this for a requester in my shop, Kinda whored style but its okay. CnC welcomed And check out my shop for custom FR sigs ^_^
MJ's light source seems a bit strong and the render appears like it should have another source on the opposite side as well.
The lightning isnt strong, Its a 60 PX Softbrush at about 65 opacity, thats the picture. I see how you got the Lighting on the left, thanks for the input ^_^
The light source needs to cover both sides of the face, try to avoid these type of render/stocks. And the current light source is too bright. Also it looks like you just threw the render in the sig, doesnt blend in well with the sig itself.
