I looked at the images for Mariny's texture on his/her website and that same darkness is on the knees. I dont think its the model. Its the texture itself.

As for the nipples on Pankos texture, I couldnt find it in freestuff, but I suspect again, its not the model. It might be the texture was created for large nipples?? Just a guess.
