#1 was the one that originally caught my eye.
Well framed and composed... with a pretty girl.
A stone cold keeper
#2 fell apart on you; too much clutter and I assume the chair was the subject. If so, not completely in the frame, and a better angle could have been had. Remember to take full advantage of your cam shooting height; use any height from floor to ceiling, whatever gets the best shot composure.
#3 I like a lot despite some flaws; it has impact.
#4 is a great shot, I love the huge open spaces and the concrete columns.
Great subject, cam position, composition and framing.
My only criticism is the group positioning; positioning is too symmetrical.
Read/study up on music album cover member staggering.
It is an art form in its self. Maybe the person on the right should be a about 5 feet closer to the cam, looking towards it.
I have no comments on film speed, exposure and the related horrors of film shooting. I'm not familiar enough with film shooting to give a fair and accurate assessment.
Obviously there is little post processing.
This could improve the images,
however I like the rawness of them especially #3.
The whole shooting into the light of #1 & #4 I like a lot as well.
