A strong sense of narrative - I am really glad you weren't tempted to crop/frame in closer, as the entire scene makes for the story. Very nicely observed.
Good going making the top20. Really like this shot. I must say the 2nd page looks very good, and you're in good company with Mak's, Tim's, Wenders' and Armin's fine shots.
I think this tunnel was used in a movie about a child who used to be an adult and he visits his old lover and messes with her. Oh well, anyway, for this reason it is a little emotionally dark and more interesting to me than it would normally be. Perhaps this is intentional?
