I really like the aesthetic to this set,
The juxtaposition in number 1 is awesome!
I would of liked to see the results if your feet were a bit braver and you got closer to your subjects, the bikes in number 3 don't work for me, and the same with the white car in the last, however, I think the subjects are interesting in themselves.
I like all these shots but in particular I do like number 4, the street in the rain. I have never used this type of film but might give it a try. There is something about the contrast range you get from film and a rainy street that has always appealed to me.
