This is one of those photos that I think the photographer loves more than the viewer. One of the hardest things to do is to make something *you* like, into something everyone else will like. I struggle with that all the time myself.
For me, this is a very uinteresting photo. It's not a subject that pulls me in, it's not a composition that makes me say, "wow, that's different", etc. Of course, I don't know the reason why you think it's interesting, but it just doesn't have the appeal that is needed for people that *don't* know.
Excellent textures in the wood. I like the subtleness of the colors in the sky and water, with that slight pastel coloring on the horizon. Very nice. The composition is also very good - I like the angle of the dock
