00:05:722 (4,1) - i got your idea, but how about change spacing between these objects to best represent loud piano on 00:06:065 like here 00:04:180 (3,4,1)
00:10:865 (2,1,2,3) - you can enlarge the triangle to avoid 00:10:865 (2,1) - nearly overlapped
00:18:408 (1,3) - 00:50:637 (6,2) - could just stack, these tiny overlaps slightly stand out from the map's general concept
00:21:665 (1,2,3,4) - very subjective but i think this conflicts with your aesthetic concepts cuz circles look crowded, maybe try https://osu.ppy.sh/ss/17715000/9456
00:25:780 (2) - Intentional circle? Previous 00:14:808 (2,3) - which have same sound have lots of rhythm, so ignoring 00:25:951 - 00:25:951 - feels really off. Can try similar rhythm at least.
00:26:980 (3,4,5) - slider shapes are kind of ramdom, maybe try what you did to 00:32:294 (2,3,4,5) - 00:34:180 (3,4) -
00:36:922 (1,2,3,4,1) - i think for (5) needed more spacing than now, cuz you literally killed loud drum on 00:37:094, also you can NC (5) to emphosize drum a bit more
00:52:351 (1,2,3) - try to avoid them being nearly overlapped to make this looks clean and tidy https://osu.ppy.sh/ss/17715014/f940
00:58:522 (2) - highly prefer this to be a 1/2 slider. even better if it has same shape as 00:59:208 (3) -
This 1/1 slider at 01:02:294 (1) - Could split into a 3/4 slider and a circle, similar to what you did at 00:40:351 (5,6) - or this
Having three consecutive 1/1 sliders for long vocals with almost the same rhythm at 01:00:922 (1) - 01:02:294 (1) - 01:03:665 (1) - may lead to a less engaging gameplay and a loss of contrast. Additionally, making the vocal at the end of the 1/1 slider clickable would give the map a more accurate rhythm representation.
Same applies to 01:07:780 (1) - 01:14:637 (1) - .
