I did some of this last year so here are few of my pointers.
Pick a time when there is less foot fall if possible as you ought to be on a tripod taking long exposures and you might be in the way otherwise. A remote is a good idea here.
There will be more light bouncing around if has been raining recently, but take what you get I suppose.
On long exposures, cover the OVF with your hand or the street lighting behind you might spoil a shot or two.
I just started doing PP on a more capable computer and found these below were too dark and bumped the exposure up 1ev, you could do that in camera at the start if the scene is predominately dark.
I used the SMC DA21 mm which I found wide enough for these scenes, even then I have to compose carefully to remove unwanted objects, but FL is scene dependent and a good zoom might serve you better.
If you have a lens that will make nice starbursts, this is it's party time
.
Happy hunting.
Apologies, I saved the first two in portrait, but they came in as landscape and I don't know why yet!
I have now removed them
