|*Hello from Sid and the Critique Club*
An excellent image that fits the challenge well.
Well, you've certainly found a most appropriate subject for the challenge here, and the timing is such that the tide forms some interest in the middle distance beyond the dry shore. The long exposure has calmed the waters which seems to be the chosen way nowadays, personally I prefer something in between, a little more animated.
Although you have made an excellent job in terms of composition I do have a couple of issues with the image, the main one being the blown highlights. I know its inevitable that when you are including the sun you are going to get a certain amount of blown highlights but the long exposure has blown out too much of value here. I do like the starburst effect of the suns rays from the small aperture. The other problem for me is the unfortunate nature of the cloud bank which at first sight gives the impression of a sloping sea which would obviously be a definite no no. I'm pleased to see one of your commenters making the effort to expand upon the normal one liners, he adds another interesting perspective.
Well done with your deserved high placing for yet another excellent image, Sid.
