I was pretty happy with my original homage to Underworld, as I learn more I keep wondering if I could do better. In the meantime, I had updated my Selene character morphs, and found better wardrobe items. I also thought it appropriate for her to have her guns up, in frame, for a more dramatic scene. In my first attempt, I had to tweak the lighting quite a bit in post to give it an authentic Underworld feel. Now, I understand Iray lighting and tone mapping well enough to achieve most of the lighting in render. The tone mapping made the image a bit too cool, so I did do some color and contrast adjustments in post for my final, updated, image.
