Thanks! The highlight details are from normal maps.
Yes, there is SSS, though it's pretty subtle. I thought having the SSS map multiplied with a red RGB node looked a bit better than with just the SSS map which looked a little too bright on the shadows to me...
But what do you think?
EDIT: Hmm... I've been having some trouble on Firefox viewing accurate colors... For some reason my Photoshop keeps trying to view (and apparently save) pics in CMYK proof-settings or something...
If the middle pic looks different from the original render above, that's why.
