I see you started to make good use of her lol, nicely done mate. Can't wait to see what else you do with her, and I would love to see the other version of her as well lol... I mean small boobs will make her look underage lol, but it will make her more unique, v.s. all the sexy DoA girls, who have those big boobs, you should try to render with cycles, have you used sss in this image?
Yea it is quite a lot to learn those materials, but if you need some tips if you do choose to start using blender cycles I could give you some materials. I have made an excellent skin shader which makes renders look oh so beautiful lol. But as I can see you are a pro at the blender internal lol, I am such a noob when it comes to the internal, I never really had a chance to get it down. I mean I know how to get a killer skin shader in it, but thats about all with materials lol.
