Hi John,
very interesting shot... was there a particular reason why you didn't shot the panorama wider? I think it would have had benefitted the comp to have a bit more on the left and right... also, did you do a b/w-sepia treatment on it, or is this the remnants of the sodium lights.... and my last question, since I was also contemplating abusing the roof of a car: did you jack up the car to prevent wobbling or did you just climbed up and shot it?
nice work.
