I literally have a few wrinkles to work out. I have a problem where the little splatters cause bump without coloring. These bumps are tiny - on the order of 1/200th of an inch. But when they catch the light just so, they look wrong. Click for full size and look at the arms.

Sigh.

I really can't bring myself to post the shader until it's right.

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)
