Nice shot. One issue: it might have been good to try and burn in or apply a multiply layer to recover the detail in the clouds--they are overexposed a bit. Also, I might have cropped a bit on the right--the support area there is not too "seven wonders of the world" attractive.
Nice shot, good to get the birds in like that. Seems a bit over sharpened. Is that building work still going on on the bridge? The light is a bit disapointing, seems a bit flat, (not within your control I know). Unfortunately a well photographed location of which there are many excellent examples and you are bound to get comparisons. Well done anyway, a five from me.
It's a great shot and meets the challenge well...My only constructive critisism would be that there seems to be a bit too much beach for my taste. Otherwise, great shot.
