Interesting interpretation of the word "flight," but the photo doesn't quite live up to the title. It might work better in the "Urban Landscape" challenge.
Good cityscape. Perhaps the feeling would have been enhanced if shot thru a window? It's a little dark which is ok because of the title, but I would still lighten it a bit.
The yellowish tone gives this an ominous feeling, and I like the skyline you have shown. While I can appreciate the "stretch" of the challenge, even with the title, I don't get a feeling of flight from just the picture.
I don't really see any flight here so I think you haven't really met the challenge and you'll probably get marked lower for it. The composition is interesting as is your choice of sepia toning. Somehow this photo gives me a stormy autumny kind of feeling.
I love the idea here. I think to improve it you should crop off the junky looking bottom..Of course I don't know the conditions you were in. I have been there and the wind/cold are miserable to deal with. The shot is somewhat dark but over all very good...super skyline. I'm not sure I see 'flight'.
