Quote - If I may suggest - add a MAT pose with freckles mixed in with a Blender node.  I wish more people would do that.  In fact I'd kill for a variety of freckle maps mixed in with Blender nodes (currently painting freckles onto a texture and I'm not very good at it).

 

Ok, I think I just might have the freckles maps ironed out now, the first render is with the blender for the face set to zero:

And the second with a blender setting of 0.6

Still have quite a bit of work to do on specular maps, bump maps and of course I haven't even started on the lips yet, but so far I think it's coming along nicely.
