Well I think it was quite good overall but the flow of scenes wasn't always good, I couldn't always feel the impact of the song, especially in fast part like chorus, you need to make a stronger impression than this. Also this murasakibara mask was quite awful haha. Be careful not to make too many fades, you can pull out a cut a lot more than you'd think and it's cleaner and more dynamic usually. And last: what's up with this end xD it's a bit weird to end here imo, it feels incomplete.
Other than that I liked your transitions, some cam moves were really interesting and your overlays are quite pretty, you managed it well
I don't know if you did it on purpose or not but the scenes at 1:16 and 1:24 reminded me a lot of Not just a Dream, that's funny xD
Anyways good job, keep it up and don't worry about french xD
