Skillfully executed with available tools. It does speak of Hopper who considered one person as a crowd. srt101fan suggested a different position, and I agree almost. Instead, I would terminate the image at the right side of the cube with only a small section of blank gray beyond. The vertical populated in the image beyond the cube adds nothing to the message; that which does not add detracts.

We humans are overwhelmed by the structures we have created is the message I see. I googled, "Edward Hopper and his "lonely people" paintings" and then clicked on images. Interesting works.
