Well composed. I like the line of reflection at the midpoint. More contrast and a darker or more dramatic sky might be achieved with some minor post-processing.
Thought this was some fancy photoshop thing. But whatever the technique, I enjoy the vivid colors, the composition, the faces that appear in two places at once. I imagine that was the intent of the installation, and it works! And you captured a great instant of that Art.
That's a great catch; excellent street photography. Too bad you couldn't work the pillar the guy was about to walk into into your composition! Great street photography. Love B&W.
