Text should match the style of the sig you're making, i'm terrible with text and often lazy with it... learn from me.. take your time on the text, it's as important to the sig as the designs you make.

as for the sigI like what you've got going on the right side but the render could be blended more.. try the eraser on a soft brush or the blur tool. also, as a layout opinion he's staring off into the distance but you made the distance all blurry.. while on the one hand it creates depth you don't want to foget about the overall feel of the sig
