Nothing to be unhappy about here.
You apparently know all about night photography, small apertures, long exposures and all that. The photo standing out because of its absolute clarity is 3, I think, though the colour in the sky of 2 is also nice to look at, along with the lights already coming on.
I quite like the last one, too, as I am a fan of photos that sport light and shadow situations. The shadows stretching diagonally towards us add nicely.
