One of your best. I usually don't like "tough looking girl/woman with a cigarette in her hand" concept but this feels totally different, the look of the model is not trying to say "i am tough" she doesn't need that because she looks naturally tough enough. On the other hand, doesn't try to hide that she is a human being and also as naturally fragile as a woman. Also her body language isn't trying to complete the tough imagery by showing "...and this is my cigarette!" She just holds it naturally. Moreover, she doesn't try to be sexy, she just knows she is beautiful. She is carefull, but she is relaxed, total confidence
The lighting, the black and white theme adds much to the atmosphere, the slightly seen reflection is a beautiful detail thanks to the surface of the table, the (i don't know the true English word for it) grainy/spotty(?) colored sweater/blouse(?) on her is the perfect match for the theme. Great work!
