I'm going through the entries, stopping at those images I feel have had the benefit of an unconventional eye and dwelling a little longer to try to see and appreciate what you saw. This is one of those images.
Positives: Love how you have thrown away the colour option to give us something rather deeper - a concentration of form and light and perspective. What make this is the way the whole thing is compositionally balanced and how you have avoided the ends of the grey scale range.
Critical stuff: Nope
Overall: Characterised by the subtlety of a master at work.
