Honestly, cinematography/lighting was really well done! I also really enjoyed the wide long shots of the gas station. The camera quality was fantastic but a tiny noisy, but it wasn't enough to bother me.
Also, the color grading was well done. But there were some really big flaws I think need to be addressed..
The acting felt so forced, it felt like they read the script and said it out loud is what I'm getting at. In the end of it.. I didn't really understand it all, that might be me not being smart though.
Aside from that. there was one part that really stood out to me when he was digging through his bag in the beginning. There was a shot of him doing something and it was pitch black, his phone lighting up, black again, then his face lighting up. I think you should just cut it to seeing the phone light up then the light on his face and try to make it a little tighter in that area.
You definitely have filmmaking finesse, and that's all I have to say in criticism as a fellow filmmaker. From some mates I watched it with, who are not filmmakers, your audience.. They said it was just kind of boring. I somewhat agree but it held my interest because I kept asking, "why?" The pacing was really slow and awkward, though, and I don't mean to offend you or anything by saying all of this, just trying to give my honest feedback. I think you should work on it some more before sending it in if you haven't.. Other than that stuff, you did an excellent job of cinematography.
