I love this stuff! What a difference, what potential!
Getting those masks closer to ready: here's what they look like under the skin:

and the result?

The attached picture has the shaders in place: you can see how the eyeliner in the left eye isn't quite where it is in the right eye. And, it looks like she forgot the upper lid of the left eye... but with a little more adjusting, that will all be right, I think. Yep, the lips need a bit more work, too, now that I've rendered it higher-res, but wow, that reflection in her eyes is purely Bagginsbill's! Not a painted-in reflection, but the result of a light! The specular on the lips ties in with it, doesn't it? Oh, this is so COOL!! I'm having way too much fun! Thanks heaps, Bill... what an incredible enhancement you've made to Poser!
