I have to disagree with most on number 4. I really like it, the blown highlights only add to draw my focus to Jack's face, it also really helps to define him and separate him from the background for me, more than the DOF does.
Number 2 I like as well, if it wasn't for the semi-modern sky scraper poking up this would have a completely timeless feel to it, but I still like it immensely.
Number 1 I can't put my finger on, I'm not sure if it is the leading lines taking my eyes straight under the bridge to Blues point Lavender Bay. I must admit the warmth of the morning light gives me a view of the bridge I've not seen before (I used to be going over the bridge as sun rose not looking at it
Number 3, whilst artistic doesn't quite do it for me. I like the look of it and your idea, but I think this is just a personal taste thing for me.
