I added a slight color node (a warm peach) to the diffuse and another (cool gray) to the alt. diffuse for a blend.  The effect is 

subtle, but I can see what you are saying.  Thank you again, Boni.  There is the bump map in the sclera as well, but it

is obviously too low to make a difference. I'll keep playing with this until I get something that can be usable before I try

that brow trick. ;)  I also have an idea for a scar, which I will work on after the brow.

The tats are still in piddling mode, but they have been in the process now for a week.  I've changed up those and am still working

on the decision of which to use.
