A big chill would have been a surprise for WInogrand as he seemingly was always in the right place at the right time, photographically speaking anyway. I think he would have enjoyed your image for the real people feel...
your use of space and off-kilter framing is great as is the true to the time processing.
Yes I like this. It's beautifully incomplete, with an imagined icy pavement down there outside the frame, and probably snow and slush residues edging the roads. It's a good example of how you can say more by showing less, and thus you can meet the viewer half way, rather than forcing him/her to go all the way across to your side of the bridge of comprehension. I'm a relentless fan of unfinished pictures like this. 8. Thank you.
