??how to make my renders better..u saidOriginally posted by Mickels
Its more the proportions of the Hair and Face than the actual size of the head in perspective of the body. Im not to sure how much reference material you use when your modelling but by the look of the proportions it wouldn't be a hell of alot. BTW if your rendering with 3D Max fix your renders up so they are more crisp looks like you got some grain filter applied or something.
EDIT: After looking at the face abit close I'd suggest making the jaw and cheek lines abit wider and making the either the forehead shorter or the fringe (hair over his forehead) longer
