This image certainly fits the challenge this week. I also like the varioud lines that lead the eye to different parts of the image. With more engaging light, the photo would be far more interesting, I feel.
Could be much more closely cropped for more striking composition.
Definitely crop out that bright thing sticking into the frame from the right. Infact I'd crop in enough to also get rid of that open window in the lower right.
An image with them just a touch further along the walkway with the walkway itself isolated against the black would work best for me.
