They are all very good images, but the one that I find the most striking is the third one. Of the remaining, I think the fourth (last) one is the strongest, both in terms of her posture and expression, and the way the spotlight is illuminating her. Well done.
I think this was one of my best shoots, nice and easy with good white frontlight. For me nr3 is special for a live pic and has a lot of the atmosphere in it with the rimlight on het back and the hair.
