Marguerite, I find this picture a fine example of how is possible to cut a pictorially significant frame in a common, real scene. My words are not so precise, but my appreciation is sincere.
An excellent study of this terminal, with a carefully thought out composition. I particularly like the echo of the green of the cranes in the ship. Seems just a little lacking in sharpness, perhaps - important in an image of this nature IMO.
