Grats on pulling first place, guys.
Gonna rattle off a few things I hope you find helpful. (Yes, it's constructive)
1) The first 1:10 is not relevant to the story at all. If scenes are not adding to the story, they take away from it and make it harder to set the pacing. Your story starts when the fellow walks outside with his drink to sit down on the swing-seat. It doesn't matter how he got home, or how much he likes walking through his house.
2) Check if your camera has a manual White Balance control. That will help match up your scenes. A good example is in the cuts between 0:36 and 0:46, where there's a drastic shift. If your lighting changes, it's time to white-balance again. If you don't have a manual white-balance, not much to be done, I 'spose, aside from trying to keep lighting as even as possible.
3) That dream sequence was pretty freaky.
4) At about 2:50 (waking up and grabbing book), it's really dark. That's a good opportunity to use some kind of practical light (maybe switching on a bedside lamp or similar) to illuminate our actor. Probably have to re-angle the shot as well, or we'd be looking at the top of his head. Getting creative with practicals can be a life-saver, if your lighting kit is limited.
5) There's definitely something up with the sound. I'm not much of a sound-guy to even know what to look at there. Ever hold a seashell up to your ear? That's what I'm hearing in most (but not all) the footage. Maybe it's a compression artifact. I dunno.
6) I just have to ask... was the crickets/cicadas noise really in the background for most of that, or was it added in later for ambience? You can even hear them inside, at some places. That's a lot of insects in your neigbourhood!
7) Nice call on adding thanks for the open-source music in the credits. There's a lot that don't thinking, "Oh well, it was free." Props.
I'm thinking about doing film-work for a career!
You're off to a good start.
I wish I'd started as early as you. You're already out there doing it - and the more you do it, the more you learn. The more you learn, the better you get. It's hands-on trial & error sometimes, but there's no better substitute for improvement (and the satisfaction it brings) than by completing a project, taking the lessons learned from it, and applying them to the next film.
Nice little story, with a good message.
