Thanks much for the comments, gentlemen.
John, you have articulated what I was sensing as I came upon this and began working the scene. I was only conscious of that feeling of looking through a window at the strong contrast in the landscape, but the graffiti- also a strong contrast -kept drawing my eye and I wanted to put these two "contrasts" if you will, together. The beams, also high contrast, as drawing the two sides together had not occurred to me until you said it. Thanks for the feedback, all. Not my usual.
