This head was my comeback to rendering as displaying basic models doesn't cut it for me anymore. Nor do I feel like butchering models down to lowpoly for my portfolio.
Relearning rendering was pain. Initially I was doing it with mental fail however at some point it flat out refused to render so I had to switch to 3delight. At least I could slap subpixel displacements on everything.
Lighting is AO + several lights. No GI unfortunatelly because color bleeding didn't want to work with skin at this stage and I don't feel like waiting for a bugfix.
