Not bad. I won't rehash the negative or positive comments, things like the laser-cannon sound or the door closing (the problem there is that you used the natural sound which didn't quite fit as it didn't really close fully).
- The ping-pong panning of the alarm clock sound actually bothered me a bit; I see what you're going for but did not care for it.
- I thought the bedroom scene needed a bit more lighting (or grading) to bring out just a little bit of the shadows. Not that the bedroom had to be completely lit; I like the practical lighting here but it's not quite enough.
- Around 0:30 I very much liked the low shot of him grabbing the towel. Good framing and the lighting worked pretty well.
- Again with the shadows, at 2:29 with the car death scene I lost what was going on because there wasn't enough lighting going on. The wider shot started to lose me and the tighter shot finished me off; I believe he was slumped over the car door but think you really could have brought that out more with a touch of lighting.
- Along with the grading, the whole thing looked a bit too yellow for me. I don't think the partial desaturation inside would have bothered me as much if it didn't just make the guy look too yellow.
- I use a lot of plants, flowers, and other leafy tree things in my shots and staging, so I like the idea. Actually for this project, I also liked the fact that it wasn't a bright flowery thing. The problem is obviously that it was too thin to be stable and ended up distracting, but I liked the shot composition with him framed up behind/next to it.
It was a good effort and other than the pacing of the climax I thought the editing was pretty solid and the camera shots weren't bad either. To summarize what I've written in just one thought, I'd suggest that even though your camera is advertised as being great in low light, and does actually seem to be, low light isn't the same as no light. When you're working with shadows and low levels of practical lighting you need to put extra effort in to making sure you don't lose important parts of the scene, like the dead body draped over the car door. Great grading can help to a degree but not make up for the fact that there's nothing there in the first place.
So yeah, hopefully you can take a few things away from the discussion but also be pleased with what you've done. I hope you'll share more with us.
