Excellent images indeed. I like the basic lighting .. for image #2, maybe the light could be higher to also catch the top part of the hair. The low light has a slightly unnatural feel.
Skin gloss under studio light is always difficult to deal with. I don't like "editing" the skin (I really never seem to get the proper results because of skin texture changes). One way around that I like is to use frequency separation on the image and edit only the low frequency (essentially colour only) and move the colour intensity around without changes to the skin texture.
