instead of https://osu.ppy.sh/ss/15481987/16df change it to https://osu.ppy.sh/ss/15481996/4819 (placing the new combos can't be perfect since the emphasized beat is sometimes a sliderend the way you mapped it but it's fine)
from 00:00:028 - 00:06:483 you use custom clap hitsounds on every other beat, but the hitsounding is identical to the song's percussion from 00:06:483 - 00:12:179. the song uses percussion from 00:06:483 - 00:12:179 to change up the beginning.
to put it simply, using those custom hitsounds from 00:00:028 - 00:06:483 makes the entire first third of the song the same thing on repeat for 12 seconds which kinda defeats the point of the song adding in percussion at 00:06:483, so I'd suggest removing the hitsounds from 00:00:028 - 00:06:483
00:00:028 (1,2,3,4,5,1,2,3,4,5,6,7,8,1,2,3,4,5,6,7,8,1,2,3,4,1,2,3,4) - Spacing makes no sense, listen to the background tone changes, remap if possible. It will make your map so better.
00:02:876 (4) - coba disamain seperti 00:02:496 (3) - tapi di rotate 180° bakal terlihat lebih rapi, kurang lebih bakal kayak https://osu.ppy.sh/ss/15561061/6368
00:06:483 (4) - New combo missing since new snare drums kicking in, player can sightread it with the newcombo.
00:15:217 (1,2,3,4,1,2,3,4,1,2,3,4,5,1,2,3,4,5,6,7,8), 00:21:103 (1,2,3,4,5,1,2,3,4,5,1,2,3,4,5,6,7,1,2,3,4,5,6,7,8,9) - kinda confusing but I can see the syncopated rhythm you're trying to emphasize, normally the emphasis would be on every beat but if you like the syncopation here then that's fine it's just a bit confusing to me as a player
however 00:26:610 (1,2,3,4,1,1,2,3,4,1,2,3,4) - here the emphasis is on the syncopated rhythm, but the emphasis shifts from a syncopated rhythm to 00:28:698 (1,2,3,4,5,6,1,2,1,2,3,4,1,2,3) - every beat.
the way the emphasis switches up here is really awkward and inconsistent with 00:15:217 (1,2,3,4,1,2,3,4,1,2,3,4,5,1,2,3,4,5,6,7,8) and 00:21:103 (1,2,3,4,5,1,2,3,4,5,1,2,3,4,5,6,7,1,2,3,4,5,6,7,8,9)
00:15:217 (1,2,3,4,5,1,2,3,4,5,6,1,2,3,4,5,6,7,1,2,3,4,5,6,7,8,9) - Missing a lot of sounds in background, map them.
Also make the streams spaced according to the background sound intensity, adds a lot to your map.
What you were trying to here was actually pretty smart but it's too confusing
00:19:015 (2) - remove this, replace with 4 circle stream starting from the 1/4 tick before, leading the slider 00:18:635 (1)
00:19:395 (3) - slider 00:19:584 (4) - remove. Circle on the tick before 00:20:534 (1) . 00:20:914 (5) - Slider here. Replace 00:21:293 (1,2,3,4,5,6,7,8,1,2,3,4,5,6,7,8,1,2,3,4,5,6,7,8,1,2,3,4,5,6,7,8) - with a section like 00:15:217 (1,2,3,4,5,1,2,3,4,5,1,2,3,4,5,1,2,3,4,5,6,7,8,9,10,11,12) - for consistency
00:23:382 (1,2,3,4,5,6,7,8,9,10) - Don't skyrocket streams to the end, make it grow bigger continuously.
00:24:711 (2) - 00:26:230 (3) - don't use sliders like these after a precedent of using exclusively curved sliders unless there's a specific rhythmic reason for doing so.
00:25:091 (4) - add circles on the tick before and after here. 00:25:376 (2) - remove, no sound. 00:25:850 (3) - Slider. 00:26:040 (1,2) - Remove. 00:26:610 (4,5) - also remove and replace with circles on 00:26:515 (4,5,6,7). Move slider from 00:27:179 (1) - back two ticks and start stream section on the tick after that again similar to 00:15:217 (1,2,3,4,5,1,2,3,4,5,1,2,3,4,5,1,2,3,4,5,6,7,8,9,10,11,12)
kalo mau ini 00:26:040 (1) - dikasih triple aja, daripada double, 00:26:230 (2) - slidernya di pendekin dikit terus dimajuin satu di bagian timingnya trus dikasih triple
dan soalnya itu timingnya agak off yang slider makanya ku suruh pendekin trus dimajuin satu timingnya baru ditambahin triple/burst*
00:27:464 (1,2,3,4,5,6,1,2,3,4,5,6,1,2,3,4,5,6,7,1,2,3,4,5,6,7,8,9) - Makes no sense, remap if possible.
00:30:122 (4) - Heavier drum starts here 00:30:122 (4,5,1,2,3) - Maybe replace with a slightly more intense spaced stream? The gaps between 00:30:407 (1) and 00:30:787 (2) and 00:31:167 (3) carry the consistent drum sound which is abruptly ended by the slider ends.
