I think my question here is "would this make a good exhibition image ?", is the composition ok and the exposure spot on oh! and most of all is it interesting, thanks for looking.
Paul all the drama and action of your photo occurs in the lower half of your picture. For that reason I would be inclined to crop out half the depth of the sky as it is an unnecessary distraction. Apart from that your photo captures the coldness of the Atlantic and works very well in the vertical format.
