I love the expressions. Their attention goes to the subject that we see in the mirror. Jean Loup Sieff is famous for proclaiming that the prortayed should pretend that the photographer is not there. You have managed to become invisible, not interfering with the subject and as a result not breaking the magic spell. I am curious. What kind of exposures are we looking at here. Flash would have killed the mood and caused too many distractions. Available light seems difficult but the exposures are just perfect, as if the shots were taken on a sunny day outside. Impressive!
