That would be pretty cool, I mean we do pick details of what our character looks like so maybe if the face isn't shown? What would be really hot is POV images. It would be some excellent eye candy to see these characters from certain camera angles, especially if they're grabbing on to one of the main characters limbs, with the skin color and body type you chose at the beginning of the game of course.
