Really cool style. I like the video and your lighting is great. Put more thought into the camera angles and movement rather than varying it up with slight punch cuts. Also, if this had good audio like just renting a lav mic, it would be great. I would reshoot it honestly, because it's great.

Really great shots. Editing doesn't feel intentional but instead arbitrary. I would like to see more footage of your speaker, that shot is more visually compelling than the others and I feel drowned in timelapse footage. You should deepen the blacks in the gopro footage so that it matches your gh4 footage. There's a part where he says as you can see behind me, but we can't see behind him. Feel out the edits more, make them seem intentional. Cut with a purpose.

Mistake #11 shooting with an arbitrary shutter angle.

Cry me a river

It looks like it was shot on a t3i with the ambient room lighting.
