Hi Joe,
I like the crop, the beautiful light and soft muted colours. And the square crop but I can tell that something has been cloned out, ie; the water looks funny to me, even at this small size.
Personally I avoid cloning (unless it's something small and wee that is easily done) because I can't do it well, and it takes too much time, and also because in nature images it is often not permitted and/or I feel funny about it, unless the image is an obvious artistic rendition. Therefore, most times for me it's easier to just do a re-shoot. Perhaps if I could do it well I'd change my mind.
Anyhow I'm still working on improving my landscape scenery images but if this were my shot I'd crop it like this (3 x2 ratio) to just eliminate the ducks, or if you wish more water leave the uppermost duck in the image... He could be a lonely bachelor dreaming about finding a mate and sailing into the sunset with her one night.
PS My suggested crops are frequently way off base. I lightened the shadows on the bridge a and the swans, just a wee bit.
