I dont really shoot portraiture, so I'm coming almost from the point of view of a viewer. I like the lighting and processing, but I think that the framing could be improved. As a general overview, I feel that the images are cropped too tight...or not enough. To emphasise what I mean, I'll go into detail for each image.
1. While the model's eye's fall on a natural thirds intersection, I'm not sure that is the best option for this image. Showing part of the mirror and part of the seats gives me the feeling that something is missing. I think by framing lower (perhaps just below the glass), it would lessen that feeling. More importantly though, although it is a minor part of the image, I'm drawn towards her left hand that has been chopped off. By moving back a pace or two, this could be rectified and also give her foot a but more room.
2. A bit more difficult this one, overall, I like the treatment you've given it, but I wonder how it would look in landscape format, showing the whole of her legs and feet. This would remove the negative space above her head and the corner of the mirror.
3. The slight angle doesn't work for me, but similar to the others, I think slightly different framing would help, going slightly lower and to the (photographer's) right.
4. This is probably my favourite of the sequence and the B&W choice helps. However, framing a little lower would have included the whole of her hand.
5. Again, I think it would benefit from taking a step back to give more room at the sides, particularly her blouse on the left of her shoulder. The downside would be that more of the distracting pictures would be in frame, so maybe some processing to make them less prominent would help.
Having said all that, I couldn't have done any better and you've got the lighting pretty much spot on for me. I would advise thinking about what is in frame (and isn't) and whether it helps add to the image.
