I like the composition in this, and the balance between the people and the birds. Also, I think black and white works well, because the background isn't "blurred out" so it could be fairly distracting, I would think
Love the title. It aroused my curiosity enough to break out Google and track down its origin. Can't say I'm a great Mary Poppins fan though!
As for the photo, it is a good street scene, but the birdfeeder kind of gets lost amongst the rest of the scene. I guess I'm a fan of 'in tight' crops.
