My first thought was "too busy", but then I kept looking and realized that's the point of this scene and it's appeal. A thick, man made forest of masts.
OK, I'm going through the Free Study submissions, purposefully finding those images I think are shot with a less conventional eye - this is one of those images! Thanks for offering something that isn't just DPC friendly eye-candy (though of course there's nothing wrong with eye-candy):
Positives: Wow, what a busy image! Of course the busyness IS the image, this creates an abstract pattern which effectively creates an overlay effect onto the scene making this shot more than the sum of its parts. You were quite right to offer this in monochrome and your manipulation of the contrast emphasises the oh-so-important vertical lines in this shot. Your placement of the boat towards the left side of the image is critical to the shot - to borrow a boating metaphor from your image, it anchors the shot. It is that boat the eye latches onto and it acts as a primer to the rest of the virtually encoded image, allowing the brain to make sense of the rest by offering the vital context of the scene.
Critical stuff: I'm not sure I have any; I do note that there is very little that is actually white in the image and I wonder how a tweak in levels might look, but then it would be a different image and this one is just fine.
Overall: An image that keeps the eye and brain busy and one which manages to almost create an impressionist image from an 'ordinary' scene. Great job.
