In post, you should use your 'scopes for targeting your levels when you're color correcting. Most of the shots (specifically the ones with the camera pointed toward the sun) look washed out, which can be fixed by doing minimal color correcting to make sure the whites just touch white and the blacks just touch black.
To help avoid the washed out stuff, be REALLY careful when shooting toward a light. A lens hood / matte box / french flag to help the light not directly hit the glass of the lens would prevent some of that in those shots. Careful framing would help the others that the french flag couldn't prevent. The bright wash on many of those shots is the surface of the lens elements being illuminated by the sunlight directly hitting the glass. This is generally considered a bad thing and is usually easy to avoid once you know to look for it.
The pacing was good. It seemed like more of a fun test than a short with an obvious plot. Careful blending of the gunshot hits would let them blend more convincingly with the shots, if not darkening the shots slightly, then lightening the hits to match the raised blacks. If you're editing on a PC, don't trust your monitor to show you true black (not really on a mac either, but they tend to be closer out of the box). Always use your scopes to match exposures... specifically the blacks in the case of PCs. With an internet expectation for distribution, aim for 0% on the black (some broadcast uses 18IRE which isn't quite 0% -- and I get the impression some Windows based editing solutions target that by default).
