I see the urban but not the chaos. The graffiti is chaoitic, I guess, but the buildings in the background seem very orderly as they step their way up to castle or fortress atop the hill. I really like the picture as a whole, with the steps in the foreground leading down and the buildings in the background leading up, but I don't see busyness.
The busiest photo I've seen. Love the composition on this one. It had a bad balance of light and dark, though. Perhaps some fill in flash might have given the foreground a bit more light to balance the hazy background. Still, an excellent photo.
Wonderful montage of colors, angles and textures. You present an interesting dichotomy with the idle waitress and empty cafe. Your picture might not score as well since some will think of it as a non-busy focal point, instead of a contrast that emphasis's the busy cityscape.
