"oh that's nice" is what popped out of my mouth when I saw this. keep up that kind of seeing and you can't go wrong. I wonder what it would look like warm-toned in sepia? To me it is more of a happy warm-tone composition.
I think this is extraordinarily well composed and executed. You have included only what needs to be shown to tell the story. I love the lines of the concrete structures, and the fluid, organic form of the boats. I think the image tone is just right as well. Bravo!
