Hey Eric,
Parkour is very cool and it was fun to see in the video. I liked your opening - the fast cuts, the natural sound of 'up up up'. I was distracted a bit by the jiggly camera though. I kept hoping you could get it locked down quicker. :)

After that, for me, it became more pedestrian. The pacing of your edits slowed way down, and the narration felt too static, too traditional for this kind of story. It had that local TV news story feel - which isn't always a bad thing, but I thought this deserved something more maybe?

I was less interested in the practical stuff you focused on - how good the courtyard is, how parkour works. I wanted to get inside their heads, or see a funnier take.  Why?? Why do they do it? That's the unanswered question for me. What kind of person spends their time jumping over things that the rest of us walk around. Do they find themselves jumping on chairs at work? Getting from their bed to the bowl of cereal in the morning without touching the floor?

I also wanted more natural sound - you give us a taste of them giving instructions and we occasionally here a little of them working but I wanted a wireless on someone - their breathing, the sounds of their hands grabbing...their feet hitting the pavement.

Maybe a wireless run down their pants, the mic clipped onto the bottom of their pants?

Sorry, all of a sudden this sounds way too critical. It was fun to watch and a fine daily video - but I know you want to raise the bar on your own work. And it's way easier to tell you how to do it than do it myself :)
