I was noticing this not as much on the screen, but after I got the prints back from Ofoto. Some of the shots make the skin look downright plastic. I haven't tried altering the red curve yet as you have, but I'm headed that direction next.
The other thing I'm noticing about ofoto is how the greys generally turn out darker on the print than on the screen (with Adobe working space). I've just found the Ofoto color space file from jetcityorange, so that's going into my next round of prints to see how they turn out.
