Would of been even better if there was just one person sitting on one of the end chairs, maybe no one around for that to happen, except you, bumping up.
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: Great scene, wonderful sky. The isolation of the benches is palpable (as benches often are). As our eyes settle on this scene, our curious brain becomes aware that they are pointing this way and the urge to turn around and see the view behind us, the raison d'ĂȘtre for the benches is very strong indeed.
Critical stuff: I do like the processing - its the sort of thing I would do myself but I think it is a bit overplayed - a more subtlety toned image may have been quieter but more powerful.
Overall: I really like it - I just wonder how it might look with a little less of your will imposed upon it.
