hi !
General
inconsistent .osu file version,this can be fixed by editing something in every diffs , just to make some changes
also inconsistent TitleUnicode ArtistUnicode so you have to add them manually in .osu files
Quiet
01:24:681 (3) - miss clap at repeat point here
Restful
AR-1 ? , it feels too fast for this diff
01:06:008 (5) - whistle here as it sounds similar to 01:04:783 (2) - (tik tik)
01:15:498 (3) - ^ tail of this slider , quite similar reason
01:20:702 (4) - ^
01:25:600 (7) - ^
01:29:579 (2) - last point only ^
01:57:743 (1) - miss clap at the tail
02:16:722 (3) - maybe clap with S:C2 is good enough for the very end here
Tranquil
AR-1 ? quite fast imo , like Restful diff
00:35:396 (2) - move left and up both 2 grid (will be x:452 y:252) it will balance spacing better
02:02:334 (3) - head of slider here , normally you use whistle for cymbal sound in the drum but this point , it sounds awkward so it better be drum with S:C2
same idea
02:07:232 (4) - head slider with S:C2 clap again orz...
Spinboxer
fine but.. don't forget to update the version , titleunicode and artist unicode after being done this !
Peaceful
00:48:100 (1) - is this intentional? , this spinner is too fast and suddenly followed by a slider so maybe shorten this spinner 1/4 beat ?
01:23:151 (1) - clap ?
01:33:253 (1) - from this note to 01:36:926 (8) - , maybe reduce volume for this section to 30-40% ? and gradually increase its volume to 70 at the end of the part (01:36:926 (8) - ) as the song sounds like a slow part before the chorus so it might be a great idea to gradually increase the volume inside this section (something like 30->35->40->45->50 on the volume)
02:06:773 (6) - add new combo here , will automatically shape a star and easier to read
Taiko diff is fine but you should make an update (maybe move one note > update , and then move back to the old version > update)
Call me in-game when you are done !
