I would not have thought this illustrated pollution without the title. Image is a little soft. Caused by the long exposure no doubt. The starry sky looks great!
I'm an astronomer and I hadn't even considered light pollution as a possibility for this challenge. I like the concept. The lighting of the foreground if very nice. Wish the stars and moon were a little sharper.
This image doesn't have anything specific too focus on that is it's biggest flaw.. we can see the light has been exposed well but maybe slight illumination on the bridge might have created more interest..
