People Nanghia (A little Racy, but Probably SFW)

Some studio pics I took of a lovely young girl. This is my second go of portrait work in my home studio, and I'm feeling a little more comfortable with my space/light/talent limitations.
C&C REALLY welcome!!!!!!!!

I think you're heading in the right direction, but slightly off in all areas: lighting, pose, framing/composition, hair. Shot 4 has the best lighting, but a little too much space at the top and her hair isn't very neat. With maybe the exception of shot 2, most are not ideal poses for the model or the best angles/crops. Watch the hair, poses, and framing and with some slight tweaking, your shots should get better.

Also consider using your lights differently to get a more creative highlight and shadow balance to bring out texture and depth in your portraits. Whilst your shots here are adequately lit and well exposed, the light is flat on the subject which is not as interesting or flattering IMO.

k-9 and Ash - thank you both for your c&c - it is well appreciated. Ash - I think I get so hung up on harsh shadows on my backdrop, I literally forget to look at the model.......I don't know if it's because I have such limited space, or over thinking everything too much. My brother (a fellow Pentaxian) moved lighting around during a break to give a much better effect on her face, but it cast strong shadows behind her. Do I need another light? I have three right now - one as fill, one behind her shining on the backdrop and one diagonal from the fill above her for highlight. Help

I think that on #2, you need near-perfect symmetry to pull that shot off. To put it crudely, the gap between her legs needs to be centered right between her boobs.
