That first one is stunning. The second one is excellent too.
I like the street shots with a solitary figure, some with shadows. Very cool. I don't know if there's a need for cropping, although I tend to shoot tight which is somewhat from shooting sports/hockey and partly just my way of framing and keeping visual distractions out of the frame.
I think #6 could almost be two pictures. One of the brick building and the solitary figure, street lights, white building off in the distance. Another of that building to the right, great light and dark going on there above the road signs that could be a photograph itself.
The last one looks like it could almost be from another era, maybe the '50's, a somewhat timeless 20th century effect.
You have a good sense of how to use balance or almost off balance and it works. I was thinking about #6 then looked again and realized it's spot on thirds. Not that that's always needed or used in a composition but it's there in a number of these. You have a good eye and did good work here.
