great capture, from the thumb it looked like a water ballet. the people are distributed so evenly, you could think this is staged, and the man on the stairs is the director with his remote control...
this is really nice, nick. i love the composition and especially the title. it does look like everyone has their own personal space and avoid entering to other's space (well except that couple around the middle). and the guy sitting on the stairs is a nice addition to the composition to break the monotonous flow in one direction.
