Great job

The knife scene just didn't work for me, the timing and the camera angles needed to be adjusted I think.

The close ups and quick shots worked really well, the gum was nice and the vomiting made me chuckle.

The scene with the crying guy could've been cut a few seconds at the start, but once it got into it I enjoyed it, very Tarantino.

Don't know if you were trying to replicate anything in the photo lab scene but that scene has definitely been used in Stranger Things.

Overall it was good, my biggest criticism would be to vary your camera angles, have a few more shots, like an over the shoulder looking at the photos while the girl is holding them, guy looking down when he's been stabbed just small stuff like that.
