I'm exchanging PMs with Santel now. I have a couple questions outstanding for him to confirm, but I think I know what happened.

Santel got displacement from VSS that was not intended. (That P6 problem where the displacement gets used when it should not.) So the nose, lips, eyelids, and ears are all fatter than they are supposed to be. Santel did not realize I had no intention of forcing displacement on his figure. He only had color maps on it - nothing else.

As a result, the nose is no longer "chiseled" looking and the lips are fatter than they are supposed to be. And he hasn't confirmed, but I suspect that the areas we saw touch-up were the result of "crossover". When you apply displacement to surfaces that are very close together, they "cross over" each other and you get a render artifact. He probably fixed them in post work, instead of simply removing the displacement altogether.

Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
