Hopefully you remember what I said about perfect stacks. There's only I few that I had issues reading but I'll go through and point out some stacks that need fixing along with everything else.
Notes like 00:03:022 (2) - And 00:04:942 (5) - In general you should probably stack normally below the slider ends. Just makes it look cleaner
00:04:462 (3,4) - Normal stack these, looks really weird at 0.15x spacing.
00:21:502 (2,3,6,7) - Don't see why you made the first set a perfect stack and the second a normal one, keep them both the same. Might be better to just c/p this and similar repeat sections and stacking them normally.
00:26:422 (5,1,3) - Move these up a tiny bit. Stack the 1 ontop the 3, the same way you did it with the next combo.
00:28:822 (1,2,3,4,5,6) - I feel like this section might look better if you just c/p this combo and then keep rotating it each time.
00:36:502 (1,2,3) - Spacing here is uneven.
00:38:422 (1,2,3) - ^ But this seems intentional, and it flows well so its fine either way.
00:41:302 (1,2,3) - Again, uneven spacing.
00:43:342 (1,2,3,4) - ^ (Fine either way)
00:44:182 (1,2,3) - ^ (Fine either way)
00:54:262 (3,4,5) - ^
00:56:182 (3,4,5) - ^
01:00:022 (3,4,5) - ^
01:08:182 (3) - Shape this slider so it doesn't overlap with the previous one at the end.
01:12:022 (1,2,3,4,5) - Might be better to space this evenly.
01:14:182 (2,3,4) - I had trouble seeing this stack when I first played this. Stack them normally instead.
01:16:822 (1,2,3,4,5,6,7,8,1,2,3,4,5,6,7,8,1) - This stream is so ugly, pls fix. Switch the spacing and combo every 4 notes as well.
01:24:022 (3,4,5) - Spacing.
01:26:182 (4,5,1) - ^
01:26:902 (3,4,5,6) - ^
01:28:822 (3) - Blanket this better.
01:39:382 (3,4,5) - Spacing.
01:40:582 (4,5,1) - ^
01:45:382 (4,5,1) - ^
01:46:102 (3,4,5) - ^
01:48:262 (4,5,1) - ^
01:50:902 (1,1,2,1) - The way this is stacked makes it seem like a normal stream, might be better to move 01:50:902 (1) - off the stack to make it more readable. Same goes for later on where you used the same pattern.
01:51:862 (2,3,4) - Readability issues with this one first time around as well. Stack normally.
01:53:302 (1,2,3) - Try and keep this triple identical to ^
01:54:982 (4,1) - Normal stack these.
02:02:182 (2,3,4) - Stack this normally like the last two, just for consistency sake.
02:04:102 (2,3,4) - ^
02:04:822 (1,2,3,4,5,6,7,8,1,2,3,4,5,6,7,8,1) - Refer to what I said about the other stream.
02:12:022 (3,4,5) - Spacing.
02:13:942 (3,4) - Stack these a bit cleaner.
02:14:902 (3,4,5,6,1) - Spacing.
02:15:862 (1) - Id put the preview point right on top the white tick here personally. Also Mute the slider end w/ Soft sample.
02:23:542 (1,1,2,1) - Same as before, looks like a normal stream, unstack the first note.
02:24:382 (2) - Blanket looks a little off.
02:29:302 (3,4) - Stack these properly, same as I mentioned before.
02:30:262 (3,4,5,6,1) - Spacing.
02:38:902 (1,1,2,1) - Same issue as the last two.
02:44:182 (4,5,6,7,8) - Spacing.
02:49:462 (2) - Stack this under the slider end normally instead.
03:15:862 (1,2,3,4,5,6,7,8,1,2,3,4,5,6,7,8,1) - This is fine but it just needs fine tuning to make it a smoother circle.
03:25:462 (1) - Move this down to make a triangle with the previous two notes.
03:33:502 (2) - Stack normally under the slider.
03:33:622 (3) - I think this might look better if you blanket it around the previous slider instead.
03:39:382 (3) - Blanket isn't perfect.
03:41:782 (4) - Nothing wrong with this, but maybe try something like
https://osu.ppy.sh/ss/3717246 (The 5 is a little off but you get the idea)
03:42:742 (1) - Stack this on the previous slider.
03:45:622 (6,7) - Normal stack should work better here.
03:48:022 (7,8,9) - Spacing.
03:52:822 (3,4,5) - Spacing is only off by a tiny little bit.
03:53:302 (6,7) - Stack normally.
03:53:542 (7,8,9) - Spacing off a little again.
04:15:382 (1,2,3) - Spacing.
04:19:222 (1,2,3) - ^
04:26:182 (2,3,4) - 04:28:102 (2,3,4) - Try and keep these two the same.
04:28:822 (1,2,3,4,1,2,3,4,1,2,3,4,5,6,7,8,9) - Same as before, just needs smoothing out a bit.
04:36:022 (3,4,5) - Spacing.
04:37:942 (3,4) - Stack normally.
04:38:182 (4,5,1) - Spacing.
04:38:902 (3) - Start this combo stacked under 04:38:422 (1) -
04:38:902 (3,4,5,6,1) - Spacing.
04:47:542 (1,1,2,1) - Same as the last three.
04:51:382 (3,4,5) - Spacing.
04:51:622 (5,3) - Might look better to start the 3 stacked under the end of the 5.
04:53:302 (3,4) - Stack normally.
04:54:262 (3,4,5,6,1) - Spacing.
04:55:222 (3,4,5,1) - This is a similar case to a few other sections I've pointed out. With the equal spacing it looks like a stream, try spacing the slider differently that the triple, or just move it so it isn't in line.
04:57:142 (3) - Move this a tiny little bit so it isn't overlapping with the previous slider.
04:59:062 (4) - Fix blanket.
05:02:902 (1,1,2,1) - Same as all the others I pointed out.
