If only you used Alex Brandt's saxual edit of this song.
Shaders didn't fit the song, it's a love song so you should've used some red/white or some red/black. Not green.
Sync was fine, but it's better to slow down and speed up a clip a couple times rather than have it going at a constant speed so you don't get people telling you there's no sync.
The parkour replays weren't that good and don't really deserve to be in a video, get some off the ORMO board or some well-known players' replay threads.
Always disable resample when you're editing, it gets rid of that bad motion blur that makes the quality of the video look worse.
