@Birddie:
Right now I got a more precise description where the TOS violating part of the image is: It is a view onto the back of an adult woman, and my render-programs (first Poser, then Vue) rendered what you can see in reality too.
Whatever it may be, the mod has seen "the inner portion of the vulva or vaginal area" (in my view it is just the rear part of this area, but I'm from Germany and don't know american technical terms very well. Probably people of the Middle West say "inner portion" when they mean "rear part").

So I have been allowed to repost it if I cover this part. However, dear mods (that's why I began this thread!), this picture is part of a story, and I have no clue why or how or with what this part should have been covered. Guess I must invoke the Big Black Shadow (I'd hate to mutilate Taika's sex, better paint it black... anyway, it is weird too).

@svdl: Really, I am close to leave Renderosity, and I am upset because I really tried hard not to violate the TOS, but they have seen "something" anyway.

Now it might be really the best if I'll send all half-way suspicious images to the mods first (sorry, while writing this I feel free like a novice of the Holy Inquisition), but I intend to post the complete series - uncensored version - to another place you surely know (but we don't tell where - this would violate the TOS too).
