So I am coming in very late here to say, Woohoo! Did you get a chance to give the software a try? It has a bit of a learning curve, like any program, but there are good tutorials around, and there's a ton of free content at places like ShareCG dot com. Hardly anyone in fandom seems to be playing with it, which surprised me -- I only know one person here at Dreamwidth who uses it (and someone else who made some fun images for Kink Bingo a couple of years ago), there are only a few 3d images at AO3, and there's only a scattering of fanart around deviantART and some other sites. I'd love to see what you do with it, and if I can answer questions or help in any way, please let me know!

I've been working with the Michael 6 model to make Jacks and Daniels, but if you haven't committed to any particular figures yet, I'd recommend the Genesis figure. It's got a lot of flexibility, there are some great free morphs for it, and it works with FaceGen, a program that can shape faces and heads for you using photographic references. The free version includes a kind of watermark on the output, but it's not too hard to clone out with Photoshop or the Gimp. Here's a site with downloadable examples: relativitybook.com/CoolStuff/facebank.html.
