#1 is very nice. I think that the most interesting parts are the vertical supports, and their shadows -- so I wish I could see more of those shadows! The colors are nice and warm, which is pleasant for this sort of sunset (or sunrise?) photo.
#2 is very bland. There just isn't much for my eye to see. Sorry.
#3 is better, especially because of the mist rising from the water. But again, it's lacking much for me to look at -- it's a good start, but could use even more reflections, clouds... something more to look at. Also could use some straightening.
