So, as usual, I've been working on not making progress with VSS. Instead I made progress with matmatic and VSS shaders. The new shader is more "physics" based, instead of me just empirically connecting somethings together and guessing at how it should behave. I have multiple layers set up, and each layer "takes" some of the incoming light and does something with it. The next layer only gets what the layers above let it have.

I thought I'd show you the results and get opinions since I've been staring at it so long I can't see anything anymore.

First the VSS Preview Release 2 skin shader (PR2).

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)
