Horizontal lines dominate this picture in my eye. You could have cropped a chunk out of it with the bottom of the boat down at an angle and had an interesting abstract shot.
Minimum contrast b&w conversion - an unorthodox graphic approach - probably will not be too popular. I think a interesting image and good overall composition, very subtle diagonal emphasis to the dock. A good dockside view loaded with hardware & nautical detail.
I can see the diagonal, but the main composition is horizontal..I love the repeating patterns (but they are horizontal). Also, the horizon isn't level. Very well suited to b/w, but the contrast is a little lacking for me.
