#1.....not keen on the trail of light leading through the middle of it.
#2.....The sky and stars above the quarry wall are good, the light on the quarry wall is good, but what are the coloured lights about bottom right?
#3.....I like this one, it would have been much better with all of the tall tree in the frame.
#4.....Not my cup of tea at all,i`m afraid.
Just my opinions........
The only one I don't like is the first where the foreground shadow is putting me off. #4 is great with fabulous colours. I like #2 and #3 for the way the small sources of light work in the dark. There's some great colours in all of them. What is that source of light on the left hand edge of #2?
I like 2, 3 and 4, I'm not sure about the path of light in the first one. That blue bit in the middle of 2 is an interesting feature. Russell, it looks like light pollution reflecting on a cloud, based on the clouds in 1 and 3, it looks like there's quite a bit around that are, having said that it's framed the Big Dipper rather nicely.
