00:02:027 (3,1,2,3) - Basically you need to improve your visual spacing to fit this style better. As you can see, most of this objects have different spacing among them, which kinda makes it feel more amateur than it should considering that you can make a good structured map. It happens quite often, try taking a look and fine tuning the patterns.
00:28:578 (2,3,4,1,2,3,4,5) - same happens here but you need to improve the flow organization. Whenever you want to switch to linear flow, try to make sure it happens because of the song and it is tied up neatly with the map.
your hitsounding is weird in some places. like 00:30:992 - 00:31:682 - should be soft hitfinishes and drum hitnormals (or whatever your kick is) cuz there are actual cymbal crashes there and not just deep toms. a lot of other places have this issue, like 00:52:372 - this part has a lot of finishes that would make more sense as soft set. go through and make sure that wherever has actual cymbals you use soft hitfinish.
other than that issue, there are places where the emphasis implied by the hitsounds is not represented by the mapping. like 00:29:096 - has a cymbal crash but its a slider end, same for 00:31:682 - 00:41:509 - , 00:25:130 - has a cymbal crash but low spacing, and so on. make sure the hitsounding aligns with what you actually emphasize with the spacing and movement and rhythm. this probably applies to other diffs too.
00:00:820 - the spacing in this section is overall way too high, it's a calm intro part so having this type of large-ish spacing and sv feels out of place (it's comparable to 00:06:337 - where it should be much more intense cuz the instruments and drums come in) plus it makes 00:03:406 (3,4,5) - this sudden drop in density and sv feel extremely out of place. just nerf it.
There are a lot of NC that seems to be missing / weird so i'll list them here but there could be some more improvements too.
00:17:199 (6) - NC missing? Huge change on the song
00:21:337 (5) - Missing
00:29:613 (6) - Missing or maybe at 00:29:268 (4) since vocal stops?
00:33:406 (5,6,7,1,2,3,4,1) - Either NC at 00:33:406 (5) or 00:33:751 (7) because the song changes and delete the NC at 00:34:958 (1)
00:40:474 (1,2,3) - Makes more sense for the NC to be at 00:40:820 (3)
00:55:820 (6,1,2,3,4,5,6,7,8,1,2,3,4,5) - NC at 00:55:820 (6) / 00:57:199 (8) instead?
01:04:096 (4,1) - NC at 01:04:096 (4) ?
01:05:475 (1) - For easier reading, remove this NC [ NC only on 1/1 rythm ]
00:48:061 (1,2,3,4,5,6) / 00:59:096 (1,2,3,4,5,6) / 01:10:130 (1,2,1,2,1,2,1,2) / 01:21:165 (1,2,1,2,3) - - Either use 1-2 NC or normal NC, but both together is a mistake.
01:16:682 (5) - Missing
01:19:958 (5,6,7,8) - Either at 01:19:958 (5) or 01:20:647 (8)?
Try to follow similar ideas on the other diffs [ specially insane diff ] because sometimes the NC seems out of place too
