Here's one of my attempts using the Cycles shaders and SuperFly. I got some initial ideas for a skin shader for Blender and Cycles from the Web. I applied my tweaked version to Mk2, using image maps from one of the texture sets in my library ( LiuYan character, to be exact ). I don't have any decent bump map images for Mk2, so the skin looks a bit unnaturally smooth.

There's a single area light above the model, and a spot light forward and to the right of the character. I didn't do anything special with the hair, so that's still using the Firefly materials.
