Those are very nice, i like the the third the most, at first glance i thought you bumped the camera and the lights bounced but I can see it was a bus or large vehicle that drove away. I like the light swirls it left. The second pic looks a bit underexposed or maybe flat, maybe try using the same edit settings from the third photo if the EXIF is the same. Cool colours on that first photo. Night long exposure shoots are quite a change and experience from regular day shoots, well done and good on you for getting out there to capture these.
