Thank you all for your kind words. Murat, I agree with you that the light would look better in red, but when I took the shot, i wanted to include the tracers from the taillights of the nearby Ford Explorer (you can make out the lines above the cart on the right), so I had to make a quick decision, and I thought having the green is a sacrifice I'd have to make. It does, however, add some contrast... thanks again
Intresting idea, i like it. My opinion, if you took this shot when the traffic lamp was red, it could be more powerful image :) But anyway, intresting composition.
