I was there! Lots of entertaining signs there. This is not the most clever one I've seen but the smile looks genuinely happy and the hair is ... colorful ;-) This being Advanced editing I might have burnt/cloned to get rid of the blur on her jacket (I'm guessing it's someone's OOF head but it's too amorphous to add "crowd" context to the shot).
I can't really tell you why, but I just love that bokeh traffic light! Its awesome!
This is a really cool photo, the one thing that bugs me is the blurry foreground right in front of here. I am pretty sure you could have edited that out with burning and cloning. 7
