This are the settings I used for the skin, the head uses the same settings, just with the head texture.

The bump settings I got from the posts of EmpressZario, many thanks for that.

I found I get the best skin illumination if I plug the texture in the skin node and that into the probe light node. I did turn down the saturation of the probe light and the exposure up.

The blinn node gives much nicer highlights for skin than the standard poser specularity.
