Not bad for a pre-dinner shoot, and a new type of shooting. Some tips:
For #1 image, that was a good place to shoot from with that manhole cover in the lower corner.
For #2 image, a decent spot, but maybe better a couple feet back, and twice as many to camera left to gets the white walkway strips to merge more in a point.
For #3 image, not such a good spot, or cropped too tight.
For #4 image, some don't think it fair or good to shoot people that might appear homeless...
The rest are good street type shots, with last one maybe suffering with the people in darkness so to speak.
Hope that gives you some stuff...
