This is a shot that reminds me of a scene in the movie: The unbearable lightness of being' where the star of the movie photographs Prague during the Russian Invasion. The moment here has been nicely chosen: the moment that the light turns green. It must have been a while for this to happen as there are a few people waiting. The strong B/W of the chap in the middle make this a very successful shot. Without him the shot would have been rather flat. Well done!
