I did this a while ago. They are all Genesis characters and the scene is just planes and cubes. I'm a bit annoyed at Mona's pose, since her foot is just floating there, but this took 2 hours to render and I had no patience to re-render this. (I use the default render engine in DS.) Carly is the one with the braids, Niqui is the one with the drill/curls and Mona is the tall one in the back. They are all wearing a Genesis Workout Clothing set found on ShareCG. Which surprised me since Mona has really, really large breasts and it still conformed nicely to her. Mona's skin texture is "Lilly Beth for v4" http://www.renderosity.com/mod/freestuff/details.php?item_id=70239
