nm from queue, easy song so I probably won't be able to help that much
[General]
I definitely agree with donkat on the preview point being kinda boring. Maybe having it at around 01:33:745 - would be more appropriate?
On the topic of the BG. I also don't think it's fitting. For the mood, yes. But I think it should atleast be somewhat related to Love Live or Anime in general.

Re-suggesting a note at 00:37:693 - , usually you aren't allowed to have 1/2 patterns in Kantans, but this song is
76bpm, I personally think it's fine, and I don't think BN's would complain about it either. Plus, you do it at 01:20:719 (3,4) - anyway :v
01:30:193 (9,1) - maybe have just the spinner? The drumroll feels pretty weird imo
01:49:930 (17,18) - and 01:56:245 (23,24) - ctrl g for variation?
[Futsuu]
00:23:087 (17) - this sounds like a k to me
00:30:982 (23,24) - ctrl g sounds better imo
00:49:930 (50) - k? not sure.
00:56:245 (7,8) - ctrl g again if you do the other one
01:04:930 (21) - k? Doesn't have to be a copy pasta from the last section since this one is slightly more intense.
01:12:035 (32) - k?
01:30:193 (19,1) - again think it should be just a spinner. You could also really use a break point somewhere around here
01:40:456 (12) - k? since you use one at 01:46:772 (21) -
01:53:087 (31) - ^

Can't really find anything here. Pretty damn good diff so this is all subjective.
00:22:298 (8) - k?
01:15:587 (11) - K?
01:43:614 (31) - k?
02:06:509 (4) - maybe delete this? Sounds like it's mapped to the bell but I think it sounds cool as a break point.
