When you shoot a 180s long exposure in Sydney harbor, you can't hardly avoid to get your picture striped by navigation lights of boats. It happens here and I had to remove one of them. It's not necessary but I think the picture is better anyway. Note there are still light traces under the balustrade, but I keep them because they are less troublesome.
I've also cleaned the ground a little bit and adjusted the colors to enhance the tones complementarity between the bridge, the pile, the water and the ground.
