I've taken shots like this before, I applaud you on getting it in such low light conditions! However, I think the plane wing takes away from its minimalism, so I gotta drop my vote to 6. Sorry. It's a tough shot to get, but compositionally it's weak.
Nice simple composition, but I don't think airplane wings will do well because it will alway look like a quick snapshot. I would have straightened the horizon and cropped the right 1/3rd of the picture making it more abstract.
Interesting. The colors are excellent, and to my great surprise, having the focus of the picture slightly out of focus, with the focused part used as the backdrop, actually works well for you.
