If you are planning on doing risqué (NSFW) renders yourself, and want to know what kind of work I've done with these models to help you decide if you can use them for your own work, you can see some samples at www.faemalia.com (note the spelling of Faemalia). When I say "some," I mean several hundred. Please head on over and take a look.
Just to be clear, you will see nudity if you go there. Tasteful nudity, on the "explicit" side of the spectrum, but nudity that leaves little to the imagination.
