It has an infra-red look about it, which shows the drama of the clouds. I get the feeling something is missing though. I'm not a fan of square crops normally, but I wonder if it might suit this one, cropping out the boat on the right. Normally, I would be thinking portrait format, but you would lose too many components of the image.
