00:02:500 (2500|0) - 00:04:375 (4375|1) - the 1/2 piano can be mapped here?

00:06:250 - 00:10:000 -> Piano rhythm changes here a bit and even for a normal diff it feels a bit empty. How about adding a note at 00:06:718, 00:07:968 and 00:09:218 to emphasize the chords playing?

00:10:000 - to 00:10:937 - same, the 1/2 piano can be mapped here?

00:13:750 - 00:20:000 -> Similar to another mod I feel this is too empty even for a normal diff - there's a lot of important sounds going on but it repeats the same 4/1 rhythm, which is underwhelming. Maybe you could add a few more notes for the piano to highlight the rising build up?

00:35:625 (35625|2,35859|3) - With the way this is arranged it may be a little confusing for the player to tell this is following the kick and not the main piano. You could change this a bit to make it more clear, maybe something like this?

00:36:015 (36015|2) - seems this place is just have a hat sound, it's not worth to have a note at all.

01:03:750 - better to move to different col with 01:03:437 (63437|2,63437|3) - , put these two into same cols will have mislead others to think these two drums is same, but they're not same in musical at all.

01:10:937 - Add a note here for piano? Considering it's an important 1/4 piano it feels a bit empty to only use one note here.

01:12:812, 01:13:125 - Same here?

01:17:812 - missing a note?

01:23:906 (83906|2,84218|1,84531|3) - these things is really off the music itself, please try a better pattern to express this place.

01:30:234 (90234|0,90234|1,90312|2,90312|3) - 01:40:859 (100859|1,100859|2,100937|3,100937|0) - etc
this pseudo-quad is being surrounded by some 1/2, while rhythmically it plays more interesting, consider something more normal-friendly?

01:36:640 (96640|3) - remove? https://osu.ppy.sh/ss/18991543/962c

01:39:218 - missing a note? (also this part could be slightly denser to mimick the long 1/4 stream but it will be too overkill)

01:43:359 (103359|1,103359|0) - this cymbal double is actually at 01:43:281 -

01:46:875 (106875|3,107500|0,107968|2) - For pitch relevancy I think it'd flow better if it went like this:

01:46:875 (106875|3) - to col 3
01:47:500 (107500|0) - to col 4
01:47:968 (107968|2) - to col 1

Since right now the arrangement feels a little random when they're all isolated
