I just want to start by saying, you have nailed the rendering absolutely amazingly. The ass can not be better. I mean, it's silk bending over, showing her booty to the whole world of deviantart.
Jesus christ, i can't say enough. Her thong is small enough to not censor out the junk in her trunk! If I could make fictional character alive, it would be white silk.
You seriously need to do more things like this. Let's be honest, what happened to the guy who made ass cheeks the size of Jupiter? What happened to the guy who dressed girls in minimal outfits? What happened to the guy that turned us on when we entered deviantart? Make this stuff and nothing else, at least this is what i like,
