I think this may have been too dark on some monitors and a lot of the stricter voters didn't see it as a shot where "Reflection" was the main point. On my monitor, the water is a very lovely rich green - quite nice, actually.
Not sure if it was what you wanted to do with the strong green or cyan color over the whites... I think it would be awesome with white whites and black blacks, at least around the boats. This looks like an incredibly beautiful location.
