Prepping for festival submissions

I'm looking into a couple of film festivals to submit Unknown Number to, now that I've more or less signed off on the final cut of the film. I received some constructive feedback on the film so far from people I trust, which is always appreciated. It does bring up a point, though: "festival" films can be very much their own genre, and if you really want to get in to a festival more than anything else, you have to be willing to accept and implement every bit of advice you receive (even if it's contradictory).
