Wow, really well done! Great shots, i liked the story and the acting was very convincing. The only complaints i could come up with were all sound related. The ambience track was too quiet in a few spots, the dialog had a bit of a boxy quality and the overall mix needed some compression to pull up the volume levels. The boxy dialog was the only thing that really jumped out at me though. I kept saying it sounds like they shot this in a warehouse with concrete floors. What mic did you use? You should have run the dialog through a gate to trim off some of the verb tails and then add some warmth to the midrange. Sound is the hardest thing to pull of for 48 hour films and yours was better than 90% of what i have seen.
