I thought that had some very strong points. The beginning was hilarious. I instantly found the three characters funny and unique. They had great adlib/line-readings, and the chemistry is clear (you guys are friends).
The camera work was good as well as the editing.
The idea was cool. I would personally expand on these characters and create a webseries of some kind. Make it strong though...these characters and actors deserve it.
I thought the lighting was pretty weak. There were some well lit scenes...but then others were dim, soft and flat. I think this could benefit from some solid lighting. Also, shots like the dude in the doorway...there is no excuse for that soft a shot...at one point an entire shot was totally out of focus...if you're going to go adlibby, you have to be absolute sure you catch focus on your one shot. Lighting a scene propely will help this...as well as pushing in on the subjects final mark and catching focus before ever shot.
The audio on vocals were good. I thought, however, there could be more music...a few times there were music, it added to the scenes. You don't always need it, but a little more would be nice (ie. the end scene was improved by musical moodies).
I also think more sound design could be added in general....but whatever, not biggie with this kind of project.
I think at the 60% - 75% mark of the film...it got weak and lost focus, and then came back at the 75% marker. It was so strong in the beginning, I was sad to see the energy and genuine humor go out the window...but hey...it did come back, so...
Keep it up. Shoot another one ASAP and get it out to the ether.
