One immediately feels the openness/reserve powerplay, which is so nicely reversed by the expressionless white face compared to the soft emotion on the woman's. Thanks.
Well composed and timed, I love how the eye travels from the masked face to the half amused expression of the girl and then to the definetely amused observer in the background. I also like how her hand seem to to struggle briefly to decide whether to shake hands or stay in the pocket. It says something about the situation.
