Here is the deal for me: AND IMHO. I think that headshot is way better than Crazy Talk 8 for making custom heads from Photo's.
I was modeling a head for a game character based on a couple of photographs of myself in Blender last year. I somehow stumbled across You Tube video's about Character Creator and around July they took 100 dollars off CC3, and iClone 7. I ended up spending around 500 dollars for CC, and iC, and I bought the pipeline and 3D Xchange, and CT8. Now I got pretty good at making custom heads for characters in CT8, and bringing them into CC3, and converting them.
If I would have had any idea though that just in a few months that Headshot was coming out, and what it did, I would have saved my money on the CT8. I honestly wish I could return it, and or trade it for assets from the store or market place, but it is what it is.
CC and Headshot, has basically made human 3D modeling child's play. Its pretty much automatic, unless you have specific textures, and or morphs to make an exact state, and then it may be a little time consuming. If though you are just looking for some good characters for games or art, and it doesn't have to be a perfect model of lets say Megan Fox, then you can pump out avatars all day long.
