dont take everything i say here as a rule because i'm still not sure what you are trying to do, just like you dont give cartoon artist tips to have more realistic art syles, you cant tell to a person that does montages that their videos need to be more edit-like
i'll only give EDIT cnc because you (for some reason) chose to use after effects, and calls your videos edits.
ok, now, you seem to be pretty much ignoring all cnc you have gotten so far.
first off : color correction/color grading can help set the tone of a video, to fit better with the song you chose, you can literally see that in every edit that's out there
there is no such thing as "the song didnt fit velo", velocity is a tool you use to make the video flow WITH the song, making things in the video happend with a rythm (also it was very odd of you to say that because all you did of velo is speed up the video, torixdemon sent some pretty decent tutorials on how to ACTUALLY do velo)
your keyframes are VERY solid, pretty good, maybe just go for some riskier angles that make the video more interesting, rotating the camera around the toris or going under them can help a lot with making the video look and feel more dynamic
screen pumps also help a lot to give the song more meaning in the context of the video, making the video pump with the song makes both seem kinda of part of each other
and last but not least, WHY AFTER EFFECTS? you are VERY new to video editing you just straight up picked one of the hardest and most complex editing software you can find lmao, a complex software doesnt mean your videos will be better, because you wont figure how to use the software properly, my advice for you is to get vegas, whatever version after 11, so that you can get a hang of the basic, and when you start to feel limited by the program you can go and learn something harder, but you using after effects might just end up with you being afraid of doing something new because of the unintuitive interface
good luck with your next videos!
