Well, fully nude renders would be against TOS for this, so they can't tell it's a female by looking at the genitals. That means the markers are body/face shape and boobs. No doubt with the emphasis on boobs, if what I see in the Pinup and Glamour sections of the galleries is any indication. So now I am wondering if flat-chested female adults would be welcome in the contest. Not every gal out there is a Dolly Parton, also there are women who have had mastectomies. Not to mention disabled ladies. Are they no longer beautiful enough to be in a pageant -- even a 3D art one? It does make me wonder.

 

Edited to add: And now I am thinking if it must be a purely human female, I just might enter a character who is disabled, being that way myself.
