Just a few quick renders I made as a reference for Alistair's head, using IBL (since it seems to work best when trying to light metal, like his piercings). Amusingly, I discovered for myself just how colorful his hair really is; I never noticed before, since I haven't rendered him from the back.
Set up in DAZ and rendered in LuxRender. No postwork except composition.
