You know I'm a bitch for lighting out of you PSJ [img]i/expressions/face-icon-small-tongue.gif[/img]
And of course this is no exception. Make the light directional, I suggest a soft brush very low opacity and brush white and balck in the different areas where the lighting is and isnt. Then mess with the layer opacity. Also, this bg feels like it needs something besides just brushing. Try finding some c4d off DevArt to make the bg more detailed. If the render's bg isn't in .png and it's just black, set it to linear dodge. And when using C4D remember layer masking is your best friend, just use a soft black brush on the mask and take off pieces of the render you think hurts the sig more then it helps it.
And that was random lesson 178 with Kage.
