Initial Impression:
Interesting idea, too much going on.
Challenge:
I really like the idea you had here, it's a very different interpretation of time than one would think of but still very reconizable. Good Job!
Compostion:
This is where you would lose the most points from me, I feel it's too jumbled and there's not enough focus on the action. Cropping either right below the cafe windows or right below the "Cafe Open" sign would have made this a better shot, in my opinion. It would allow the viewer to really get a feel for the situation without any of the other distractions.
Technical:
Good. Lighting is good, focus is good. Nothing really to fault in this area.
Overall:
Good action shot that meets the challenge creatively. A tighter crop would create more balance and a more focused composition.
A fun photo and title. My eyes drift toward the interesting windows, though, when I feel they should end up on the officer. Perhaps if he was in focus and with a tighter crop: but then the photo would be uninteresting. Hmmm....
