Three things strike me: the top-to-bottom light-to-dark gradient [good], the overall composition [good] and the rather mysterious material in the foreground [?].
To be honest, I'm not sure if the foreground should be a tad lighter to make the plants more evident, or made even darker to make them less so. I would not advocate cropping the bottom off, though. The h/w ratio 'works' with the subject [headland] and its placement. It helps to make this a picture rather than a 'record' snap-shot.
I think this is one pic that needs to be seen larger. And, though the gradient works. I was also wondering how it would look if the plants were a bit lighter. Sometimes one can get many good images from just one shot.
