> Quote - As a default head I have to say it's better than most, but far from realistic even as a generic form. Blow me out with some better examples.

Hard to define "better." Pagan is clearly beloved of his pixie, but she's not very realistic.  She's got pointed ears, fer crissakes. 

I do agree the one on the right in your image has a unique, real look, but I wouldn't want a figure that looked like that.  At least, not as the default.

I hadn't realized 3D scanning was that big a deal.  It's still not really affordable for the average Poser merchant, is it? DAZ claims they use 3D scans to make their figures. 

I don't particular care for realism, so I don't have their "digital clones."  I do have Dina (the above image), who was made from 3D scans of a real person, but this was ten years ago.

Perhaps someone who has DAZ's Reby Sky or Anna Marie Goddard could post their head morphs.  They were made from scans of real people.  Real people who are somewhat more attractive than average, but real people nonetheless.
