Nicely done, I dig that sky and clarity is top notch, great colors. Only thing is I feel like this has been shoehorned into the challenge by use of the title, I only deducted a point though.
Although a DC image does not say "Pink Floyd" to me, you still managed to capture the feel of PF via the unreal pinky-orange sky and buildings that look almost eerily flat. A most interesting entry. 8.
This is an amazing photo, a 9+ for a free study. The thing is for me, is that this totally sidesteps the challenge. Even if I could make sense of the title (and I can't), it really doesn't fit the mood of Pink Floyd. Perhaps another good title for this would of been "do you think they'll drop the bomb". As I said though, you really have an amazing photo here no doubt about it.
With the obvious implication of a postcard, of course. It would make a successful card, I think. A well taken shot, but it lacks a real sense of punch for me personally - it's just a competent cityscape.
