General:
Remove "Party Tonight" from tags. As said before, you don't need duplicated tags when things are at artist or title as we can already search those keywords.
Could consider naming the artist as "RAVEN" since it seems that's the preferred styling of the artist found at o2jam gameplays like
https://youtu.be/dFprcfw7pXI?si=Bie3M37GIR8MqPZA for example. Also one of the Korean music platform has them labeled as "RAVEN" found at
https://music.bugs.co.kr/track/32050348 Couldn't really found any official source regarding the artist format, so I guess you're fine to keep as it is, though mentioning as "RAVEN" feels more accurate from some relative sources.
Wonder why you decided to not add "claps" at the kiai section, that made the hitsound very empty compared to the first half. Better adding at adequate context such as
01:01:550,
01:02:445 - etc. You'll already know where.
removed tags.
Normal:
Remove audio lead-in. It's not really needed as there's enough time at the beginning.
00:26:177 (4) - What about making this slider straight? Doesn't feel that different from things like
00:24:385 (1) - etc when listening the song.
00:33:788 (2,3,4) - Move a grid left? (1,2) being too close felt messy in spacing.
01:01:326 -
01:04:908 - Could add extra notes as we're at the climax & also to avoid straight 1/1 rhythm chain being over repetitive.

Hard:
00:09:162 (7,1) - Swap NC so it gets consistent with
00:05:579 (1,3). Also
00:10:953 - add NC here for consistency with
00:07:371 (1).
00:51:475 - Add circle? Making it 1/1 felt forced for the sake of pattern while there's an audible sound behind.
Felt more normal-whistles could be used when the song has a high pitch, for example
01:15:654 -
01:16:550 -
01:17:445 -
01:21:027 -
01:21:475 - etc. Would be nice if you can review the hitsound in general and add when appropriate so the map fits better with the song.

Not bad, might need extra polishing with the hitsounds. Will do a recheck once the mentioned issues are fixed first.
