Zzomp 3D work-in-progress set requested by and featuring the model Jenny Poussin. Apparently she contacted him and they decided to work together on an upcoming comic with her 3D alter-ego as the leading girl. As proof there is even a photo on Zzomp's blog showing Jenny Poussin with a picture of Zzomp's 3D model in her hand.
This is the WIP preparation for the comic and will be updated along with Zzomp's updates.
Edit: First bunch of new pictures added (15-17). The DA variation wasn't posted in bigger size on his blog.
No penetration yet (technically there is in picture 5, oral, and probably in 6, vag/anal) because this is purely work in progress. Zzomp has not even started doing the comic yet.
@okomi again:
I'd guess Poser or Daz 3D with bought & edited models/content. Maybe some software for better lightining/texture, though I'm not sure.
Props for being one of the few 3d renders of a female character that actually have lower-body endowment to balance off her physique, instead of being just a lamp-post with boobs.
