OK I will give it a shot..
1. Maybe a little more fill
2. She looks like she is in a shadow. i.e her face is well lit from the chest up but her body is in the shade. not sure if that is because she IS in the shade or if the artificial light you used looks that way
3. Lighting looks good, pose looks uncomfortable
4. again I think it needs more fill light..colors look flat to me on this one.
5. Love this one..composition, exposure, etc all look good. only nit pick would be too much dead space above her head.
6. same as above except colors are not quite as warm because of no (gold?) reflector
7.much better use of fill than 1 or 2
8. the only thing that bugs me on this is the blown out background although the DOF is good on this one.
Hope this helps some.
