I really enjoy the light in this picture. It would be nice, as far as the challenge theme goes, if the plane was farther into the picture with a longer vapor trail. Nice idea.
I'm sorry but I just don't get it. It is an interesting city scape at night. Colors, contrast and levels are fine. Comp's okay. Great focus. But in the end I see no real relevance to theme and the title doesn't help me.
Your photo, in addition to being beautiful, seems as if you were able to freeze time. Nice vertical elements and a lot of visual interest. I think I'm looking at Toronto?
