I agree about the lighting. I'm still learning the DAZ3D program and finding the best ways to get lighting effects done right. That one (there's a whole series of both models that I did) was one of the first things I did with DAZ. The black girl was later on after some practice. Sadly, my laptop is too old to do any really involved pics, so I have to keep the backgrounds simple, usually just a 2d pic, because too many objects and the program bogs down.
Here's a couple non-erotic ones I've done using both DAZ and Bryce 7. New to DAZ, but I've been using Bryce for years now.
