After a long day I was walking down West 20th street to grab a cup of coffee at cafe Grumpy. I just spent a day photographing people and city. I was tired and was ready to take camera into the bag and call it a day. I crossed 8th avenue and walked right into this great scene. I saw a nice composition and great light. Brightly lit building in the foreground made possible to expose sky just right to make it dark blue. Sun was setting down. I quickly made several frames right before shadow from the other building consumed the scene. I discovered a bonus when I came home - somebody decided to look out of the window right when I started taking pictures.
