personally, I would like to see more coverage of the event itself, instead of just one song with similar angles cutting back and forth. It just got a little repetitive and since I wasn't learning anything new with the shots and I have heard that song so many times, I got a little bored (IMO).
I do a decent amount of event coverage and it's definitely hard work, especially with one camera. My advice would be to show up to the venue at least an hour early and film a bunch of prep: b-roll of getting food, drinks, getting their tickets checked etc. Basically, give a bigger picture of the event. Hope this makes sense. I mean the quality of the footage is great and what you have here works, but to improve there just needs to be more variety.
Hope this helps.
Here's a couple examples of same-night edits we have done for events (pretty similar formats)-
