Pete's assessment of unconventional is how I would put it, too, Paul. And also, to Pete's remark about there being more to the left, that is what I wanted when I first saw this image. I know you didn't invite critique but I wonder--and again I am echoing Pedro here--why compose the image as you did? A pier would normally want a landscape orientation so this is very unconventional indeed.
I noticed this opportunity (shall we call it) for a composition when I was walking towards the pier. I like the idea of forcing flatness to a scene you would normally assume should have depth. I could also say that I wanted to do something a bit different too but a lot of my photos lately are arranged this way so I saw it as a natural thing to do in that context.
It is extremely unconventional, but I think it is an outstanding composition and photograph. It is quirky and breaks almost every rule of composition, hence innovative, daring and original. But it also works quite well as an image, rule breaking aside.
Somehow, the attitude and strangeness remind me of a Wes Anderson film (e.g. The Grand Budapest Hotel).
