Hmm, I didn't consider about full body details, since I'm much more of a potrait guy (no big boobs swaying around here).
Still, I despise how overwhelmingly obvious the "realism traits" are in quite some textures:  big freckles, big (scale and magnitude) displacement till the age of 45, and the lips. Maybe it's me again, but some improvements seem to bring the uncanny valley to the next level. Textures won't look convincing until the shader and lighting react like it does in real life (or those contrasted catwalks, who knows.)

Vektor's "Princess" images are more akin to what I'm mentioning (without the smaller spots and subtle freckles though). It might appear to be full of makeup and a "perfect" skin, but as far as dodging that "Poser/D|S" look, it suceeds, no doubt.
