Well, if I may be one of "The Judges" that Fangman is mentioning here, I also say "too much sky" about the first photo here. It makes me want to look DOWN, further DOWN please, and just a little MORE all the time, but where there is what I (also) want to see, the photo has long ended. I do like the mountain range, but not the huge amount of featureless sky, no matter how wonderful its blue colour!
As to the second: that almost hurts my eyes, so I feel quite consoled by the third. I would still wish we were looking further down and there'd be less sky in the third, too, but at least there is (part of) that "frozen" marina to be looked at, with its repeating piers (?) or jetties (?) or quays (?) (help: which one is the right word here???), and I do like "repetition" as a element in photography.
