"6" - Was just reviewing the comments I had made and noticed this one. Very uncharacteristic for me. I never leave numbers - I didn't even vote on this challenge. So:
I love the composition of the scene. The angle of approach really lends itself very well to the reflections - well done! The close crop really works well with this composition as well. The balance between subject area and negative space is really well proportioned. The colors seem a bit washed out on the top decks, but the tonal range in the lower half and the reflections is very pleasing. Overall an interesting shot with a lot of good qualities. The only distraction I find is all the antennas/masts on the same horizontal as the subject cabins. Perhaps a bit of darkening to lessen their presence.
