To be honest I can't even do renders like those of the artists you mentioned even WITH the DAZ figures they used.  Or yeah, I'd use Roxie. and V4, and Dawn, and Antonia, and Miki 4 and Stephanie 3 and Aiko3 or whoever else I felt like using. I don't do renders. I did a web comic and guess who iI used, V4 and V3. DAZ figures. Why? Because i had a lot of stuff for them mainly. But Occasionally I pulled out some Poser figures as well if for nothing else, just plain ol variety.
