Pretty nice! I think it needs a tiny bit of counter-clockwise rotation. This works VERY well as a B&W, with the stark industrial harshness of the building and its exterior finishings and stairs, and the crisp B&W tones. Nicely seen.
Yeh, really nice photo. I'm a fan of the repetition of shapes throughout the frame. The tight rectangles in the left, moving to their shadow, and then the broad rectangles that are drawn away. Nice cap.
