This is a great shot, I don't care what anybody says.Composition is great think much better than the whole city. Also lighting I think is perfect adds to the mood. As for the "tilt" if anything it may be lens abberation.People try to be helpful I'm not dogging that but let me say if you do not pick it apart and see the whole capture(in my mind how it's supossed to be)this is VERY underated.
But then again I never do too well here.
Just writing because I found it encouraging when someone else saw what I did.
It looks like this was not a level shot. I would vote higher if level, also it would be cool to use a little longer exposure so that the lower part of the frame had more light. I like the red glow on the mountains.
Neat looking glow. I would suppose there was not a lot of light to catch this with. The tilted horizon bothers me though, and really takes away from the image.
I am guessing that you may have taken this from a plane, though if you did some of those mountains seem a little close for comfort. Regardless of how you did it this is a great take on the challenge and it is great to see how flourescent boundaries mark a city's limit
