@ 0:07 The shaky cam is atrocious.
Lighting and color balance are great. Probably could use a little post coloring of various values, though.
@ 0:30 The audio at that initial conversation is all over the place. What can you tell us about how the audio was recorded?
The over-the-shoulder shots were fine, the sequence ran a bit long but it was acceptable. I would suggest opening up the aperture some to reduce the focus on the distant backgrounds to maintain attention on the principle subject actors. This issue is prevalent throughout the film.
@ 1:36 florescent lighting, followed by...
@ 1:39 tungsten lighting. Gotta color balance each and every shot - and then - color correct some more in post. What NLE are you editing with?
@ 1:49 Is that the pole that holds up that noxious tungsten light in the background? (Don't do that.)
Need a wholllllle lotta sound blankets in narrow little rooms.
@ 3:30 Wide angle lens bends the light pole at near left.
@ 3:31 That audio is... yeah. That.
@ 4:09 Subject out of focus while background is in focus
@ 4:59 1. Hey! Someone white balanced for tungsten light!

2. Subject leans forward out of focus!
Alright, I'm just going to start jumping forward at five second intervals.
Mostly it's just white balancing & color correcting issues with a few more out of focus issues on the side.
I don't know if you want to concentrate on the technical aspects of your filmmaking or if you want to try to swing both that and storytelling at the same time.
The story was ho-hum for me - but I don't care for mysteries and detective drama not one little bit.
Personally, I feel anyone is better off making five three minute films than three five minute films. A single ten+ minute film is just a huge hit or miss investment for everyone.
Practice makes perfect and you/we learn so much from the issues unique to each project.
