Looking good, Boni, the detail is lost in shadows though.  I'm wondering if you have your gamma set wrong or you have your monitor brightness set too high, and that it's influencing your judgement on the output.  I can barely see the eyebrow details on the black babe, but on the white one I think I'd make the eyebrow hair strands thinner but have more of them, make them more dense.

Oh, and it's nice to see what looks to be a true Redhead for a change, I hardly see that on Poser characters, it's usually some other weird colour.

I was going to suggest turning the reflection down on the eyes a bit, but again, you might have set it like that due to your gamma or monitor settings - the reflections on the eyes are really stand-out super-glassy and I think that's down to your viewing settings somewhere :-)
