00:16:804 (1) - kinda off-screen, move it up a little so people can hit it.

00:56:189 (4,5,6,7) - this exact part creates different spacing logics for a 1/4 3-note stack. Make it similar to 00:54:849 (2,3,4) - so people don't get that confused!

00:59:374 (8) - It's guideline recommendation to avoid using 5-note streams. Maybe you should delete 00:59:206 (6,7) - and extend 00:59:374 (8) - on those red and blue ticks.

01:06:245 (5) - I recommend to fill this red tick. To maintain the usual spacing logic, create a note of a red tick and stack 01:06:413 (6,7) - into each other.

01:20:323 (1) and 00:14:960 (3) - sliderend is not on the tick. Resnap it by dragging the slider's end on the playfield to somewhere!

01:21:664 (7) - Slider body is potentially off-screen. Drag it to the left a little.

01:04:818 (4,5) - turn DS on and move these two to the slider, they are little bit too far from each other. Check AIMod, ctrl+shift+a and turn on "Check distance snap" box to see all of the commotion, won't be trashing the review with all of them. They happen most of the time because you do stacking which moves object by a little, dislocating the note.

00:33:196 (2,3,4) - on such parts (or some of them for variety) you could make sliders instead of small reverse since I believe it's better to introduce reverse-slider mechanics on harder difficulties, exampo: https://coffeexplainswhy.s-ul.eu/up7bfWKLuk1Sdc36.png

00:09:277 (5,1) - maybe you should move out the stack for better readability, but it's quite a gimmick so ig it's ok to leave it.

00:34:737 (5) - empty tick mapped, I would suggest to remove a note from here for better newbie's singletap experience here.

01:22:494 (3) - would make sense to make a note to remove 1/4 sliderend, the 1/4 rhythm itself is getting overused on such slider and might be unrankable atp.

01:39:196 (3) - maybe move this out to x410 y250 for more clear visuals..?

00:54:440 (6) - you could place this note closer to the previous one to follow lyrics with spacing more precise, for example place it behind the 00:53:791 (2) and then buff the whole 00:54:602 (1,2,3,4,5,6) section with the same-ish spacing.

01:09:683 (4,5) - could be a slider to nerf the diffspike and follow lyrics more precisely.

01:20:061 (4,5,6,7) - could be two sliders instead to filter out lyrics and drums to different instruments of mapping, or just one slider on 01:20:386 (6,7) - for more immersive gaming.

01:45:034 (3) - this could be a note and a reverse-slider, would represent the song better. examplo: https://coffeexplainswhy.s-ul.eu/GEQx35ClrVrbNsda.png
Notice: green note on the screenshot is placed perfectly-stacked to the last note of the previous jumping section.
