This is an intersting take on the challenge. It meets the challenge criteria imo however it seems a little cluttered to me and I don't get much of the sky or skyline part of it. Mostly what I see is the cityscape. At first I wasn't sure what the to foreground parts were but, now I see they are clouds. And I keep trying to see into the dark parts on the left and top right to see more of the "skyline" part of it but, it's too dark to see anything.
