not sure what was up with the audio, did you not notice how terribly distorted/loud it was while making the video?
Negative- audio distortion (probably due to bad audio file or you severely increased it in ae and didn't realize), little to no sync other than the screen pumps, not a very good looking shader, colors sort of matched the song, but i didn't really like the feeling of it, got a little better when the blue hue came in, not much variety in the video, just replays with screen pumps and freecam pretty much
Positive- freecam looked alright, the screen pumps weren't that bad but definitely should not be used to fill in all of the sync in a video, transitions felt decent for the way the video was, and you said you were trying out some new stuff so this alone probably outweighs every negative
Tips- make sure your audio is clean and good before uploading, work on sync, screen pumps, etc., transitions could use a bit of work, cc/shader choice could be better, and freecam could use a bit of work as well
