Thanks, everyone!
Andy, yeah, I think I'll have to give that a try. I also think I need to tweak the placement a bit as the main light source is off center. Regarding the scars, I'm still undecided on what to do there. When I painted the face, I mostly ignored them and planned to come back later. They're a bit weird as they're open scratches and not healed over scars. I figure he's undead, so maybe stuff like that doesn't heal. But I don't want to make them fresh wounds and have blood or anything. Maybe I'll try filling them in with paint to make them look like more shallow scratches rather than the deep gashes they appear to be now. I'll probably use some glazes around the edges to show some sort of response from the skin... just not sure what, maybe a bit of purple or blue.
As usual, there's a certain portion of the piece I have planned out and then there are areas that I just make up as I go. Clearly those scars/scratches are the latter. ;P
