Here goes the real mod.
Normal:
00:15:554 (1) - Consider deleting this to start with the lyric.
00:20:859 (1) - The lyric being ignored by the slider reverse didn't seemed well. Try this rhythm :
https://osu.ppy.sh/ss/84917600:47:383 (2) - Add Whistle?
01:43:359 (1) - Similar delete suggestion.
01:53:419 (3) - 1 Grid up
02:45:371 - Consider adding a spinner around here. All diff has, except this.
Rare's Hard:
00:08:968 (9) - I think whistle would rather suit at the head, than the end.
01:08:237 (1) - I think the jump is too far. Consider putting the head of the slider at (336,344).
02:02:017 (4) - ctrl+G will be better in spacing.
02:28:724 (1,2) -
I can't understand this jump, it fits nowhere D: PLEASE make a change for this. I don't think you should keep this.03:13:267 - Adding a note will be better, but no need to.
03:59:182 (4) - Same as <Collab>.
-- Either there was some jumps, most felt quite nice and not too tough. Nice job.
Collab:
00:05:127 (3) - Since this is an anti jump, an NC won't hurt.
00:57:261 (6,7) - Increase 1/4 plz, looks odd in the map.
01:47:200 (5) - Decrease 1/4. Ignoring a Clap really feels strange.
02:08:602 (1) - Why is this NC?
03:13:267 - I think here needs a note, according to the song.
03:13:907 (7,8) - Rather making this a 1/4 slider jump, placing the jump in 03:13:724 (5,7) feels better.
03:55:066 (1,1) - Make spacing like 03:49:212 (1,1)?
03:59:182 (4) - NC. This is in the blue line, and is confusing to hit since the rhythm wasn't as expected.
-- Nice diff which was fun to play, but I didn't enjoyed the 1/4 slider jumps(since I'm not so pro to manage that pattern :<).
