I usually don't like pictures with buildings and people, but this time I make an exeption... maybe because it's so gray and that way less confusing... Good thing though that the people are colourful or it would look like an old archive foto. =)
Don't tell me those cars have actually stopped!?
I like your mixture of B&W and touches of colour. I like the way it is the people who have the colour and the buildings are grey. The only change I would make is to crop the bottom of the pic just a bit, to stop the photo being a two halves composition.
