This was about half an hour after sunset. This was handheld at 1/3sec braced on the railing. It was tough to figure out where exactly the sweet spot was and to try to focus it. I think I lucked out and got pretty good focus on the left concrete thingies before the drop. The lights on top on the hill are the street lights for the interstate freeway.
What a wonderful place to photograph. You did quite well with the given lighting. Very smooth (love the way the water looks) and well focused. Nice colortones too.
