Nice shot with a lot of elements. The rocks are nice along with the ducks. I would of liked to have seen more saturation in the photo, especially in the sky. I think you could have added a little more PP to the shot and it would of scored higher or metered on the sky giving it some color. Still a nice photo to look at and meets the challenge well.
Would have composed/cropped this differently if the intention was to make the wind-farm the subject. The sky is completely white or so appears. Although it’s perfectly understood it’s very difficult – if not impossible - to get a decent exposure in such conditions and one needs to sacrifice something.
Have you considered cropping out the bottom half? I don't think the rocks and ducks add much to the photo, whereas the upper half is stunning, especially because of the strong contrast of the windmills and sea against the white sky.
-- 5 for lower, 8 for upper half, rounded up to 7 ;)
the light seems to really have done this shot an injustice - very pretty scene with the ducks and the windfarm in the background - btu the chop of the water and the harsh edged light really detracts from it for me
