I'll wait until it's finished to give final thoughts on this.

Some things I noticed:

- Text at the beginning could use a fade-in in addition to the animation. Maybe make the animation a little faster?
- Pancrop at 1:34 is very linear. It needs to be eased in, use "Smooth" setting on each keyframe, and toy around with the keyframe interpolation slider. Adding more keyframes to get exactly what you are looking for couldn't hurt.
- First parkour replay has some walls that the CC makes solid white. Exposure needs to be lowered. When creating your CC, try and get a still frame that shows the majority of colors in the shot.
- Camera paths are actually pretty good here, and seem more interactive than your previous videos.
- I think the song is pretty uninteresting, so it made these replays seem to drag working at it's pace.

For the pretty empty song, there's a little bit of editing here and there and that's good. You could find a way to sync the replays, rather than just having a blur or skip some frames every once and a while.

These replays are so cool, I'm glad you chose to make Karbn a video.
