if anyone is interested this site has a facegen demo program that will create a 3d head out of a picture, problem is the demo doesn't allow saving or exporting. but it will at least give you a glimpse of what a cf might look like ingame, and what type of headshape may work best.

this is another demo that you can change facial expressions on cf's with, some were happy, sad, mean. don't know how it transfers to live yet, but this one will let you save in the demo, but it leaves a big facefilter tag on the picture that would have to be edited out afterwards.
