When we are getting to the location that is amazing at night, sometimes it becomes even tougher to capture the sense of place, we may become overly excited and speed up our process so that we can capture everything.
Learn to slow down and feel the location, and only start shooting after you become part of it.
Lit by sodium vapour light(quite a lot of street lights over there) from camera left. This scene would be static if I set very short shutter speed, as I could see the cloud was moving and it was winding, I set my shutter speed to 90 seconds. Observation is important here, we can actually control how the cloud looks like in long exposure by watching them. This is one of the frame I'm most happy with after few clicks that expresses what I have in mind about the location.
