I like the mood in the piece. It feels like we’re watching a sunset as it passes behind the buildings on the right. The way the sun outlines and highlights the edges of the clouds is particularly impressive to me. I also like the sharp transitions from vibrant orange to dark blue shadow on the structures in the background; it is one of a sunset’s elements that has always been a favorite of mine.
