Just thought I would add a thought. Textures with "painted on" hightlights will cause problems when going for realism. I like what you have going with your lights right now, but the eyes, lips, and hair all have "fake" highlights that "clash" the lighting in the scene. When you set up your lights, do SSS, displacement or bumps, the try to avoid textures with highlights built into the map. Also, you can take your figure into post and pop the contrast and adjust the hues. bB
