Usually Unseen

This is a picture I took of a roof of a building off the M train. I go there everyday but rarely look behind me and especially not at the roofs of buildings with trash and rusted air-conditioners. My phone made the contrast between the shadow of the train station on the building's roof and the sunlight so drastic I decided to choose this image. This is also a perspective that I would have never noticed had I not taken this picture.
