Thank you. Details below in response to Sundial's questions
I used a Nikkor 18-105 lens. It was on a tripod, I believe I had removed the ND filter which I'd had on earlier for the fireworks but I can't be 100% sure. I'm fairly certain I'd taken it off by this stage though.
It was ISO160, F8, at 45 mm and exposure was 5 seconds, so not a super long exposure and I did not use the shutter release for this one.
The colors had some minor tweakings in Lightroom but they were pretty vivid SOC. I had the camera set to "Vivid" and with the wet surfaces the reflection of the lights seemed to make everything look a bit louder than it possibly was.
I'm happy to give any more detail if there is anything I have forgotten to mention
