Overall, I prefer the first image posted. It has atmosphere about it.
It's difficult to see on my monitor however, because I use an unusually high resolution, making the image small. (yeah, I could change my screen resolution, but without going into detail, let me just say that "it's impractical for technical reasons").
What I seem to see is a bit of doubling of the image toward the bottom right. I don't think it works terribly well... you could instead try a more intese gaussian type blur, with which I'd also suggest burning the area in (darkening it). Or, just try burning it in without blur.
I think it'd be pretty effective... especially if you burnt evenly across the entire bottom of the image where the street is, emphasizing the brilliant light in the sky.
I like the idea behind the image, definately. Nice thinking!
