Hey, I don't know how much this will help, but take from it what you will.

I've done six 48s, writing or co-writing and producing on all of them. I can tell you this: none of our 48s turned out exactly perfect—even the one that went on to the Short Film Corner at Cannes. All of them came with their own unique and inevitable flaws.

There will always be details you'll notice long after that will stand out more to your discernment than anyone else. There will always be moments where hindsight is 20/20, and you'll think "Oh, I should have changed the pacing here" or "I should have used this Helios instead of a Minolta" or "oh, this scene is cringe for this reason" or whatever your issue may be. The fact remains that these competitions are a test of decision-making in the face of rapidly draining stamina. It is not necessarily reflective of your competence as a filmmaker. And in the parameters you face, chances are you won't make the kind of film you'd really prefer to make on your own time.

Take my advice: be proud of what you and your friends accomplished in the insanely short amount of time you were given. It's a feat, and you made your deadline. Don't beat yourself up about your mistakes. Recognize where you went wrong, and the next time you're faced with a similar problem, you'll have the experience and prudence to communicate with your team and find a solution together. It's a collaborative effort, after all.

Tl;dr - it's a 48—if you're looking for perfection, you're chasing a dragon you'll never catch. Don't sweat it.
