I like it, but something is not quite right. I am having some trouble putting my finger on it. My initial reaction was "wow" cool composition. But then it seems like the balance is off. The girl comes out stronger (graphically) than the guy. Maybe that is because he is cropped tighter (bigger head). If his jaw were included like hers you would get a mirror effect or yin yang kind of thing.
None the less I really like it. It's a nice moment, and I like original compositions.
