Thanks eveyone for the comments. Once again they are varied which is enlightening.
Scott - Your are right there are a number of ways to crop these that produce quite different results.
Harlem22 - I know that some people don't like the long exposures but to me, for seas that are quite rough (as these were), the long exposure helps to simplify the elements. Otherwise they are too chaotic. I did shoot some shorter exposures and didn't care for any of them. On the other hand this may just be my subjective view on it because for both of these images (taken on different days) the swell was up after a storm and the wind was biting cold. I didn't have any sense of tranquility or warmth, in fact quite the opposite. Apparently that only partially came through in the pictures.
