I like the second one because it makes the bridge look very dainty and elegant. I think it is the contrast of light and darkness that attracts me to the picture. Do you feel about the crop because it breaks the rule of thirds? I like it because it breaks that rule. I think the other thing is that a catenary is indeed a thing of beauty and this picture highlights that.Anyone could have taken those photographs as there is nothing special about them.
The second shot is awesome in terms of the reflections but I feel there's something ever so slightly awkward about the crop. I cant quite put my finger on it.
Thanks for posting ignore the morons+10,000
