Unfortunately, I only had one attempt in Singapur and the weather wasn't the best, but I find the transition to night very impressive.
I took the pictures with 3 cameras at the same time.

I did the parts with the EOS R with an external timer and manual exposure setting. I then removed the strong flickering with LRTimelapse.

00:00 EOS M3 + Samyang 12mm, Interval=5s, CHDK Script rawopint
00:27 EOS R + EF 24-70mm @40mm, Interval=6s, Deflicker with LRTimelapse
00:40 G1x @15(28)mm, Interval=5s, CHDK Script rawopint
01:03 EOS R + EF 24-70mm @24mm, Interval=6s,
01:12 G1x @34(64)mm, Interval=5s, CHDK simple intervallometer in M

Nice shots and transitions.
