00:06:836 (1,2,3,4) - I'd move them a bit further apart so they don't overlap with 00:08:200 (3)
00:11:609 (2) - Move this to the previous blue tick, i mean here 00:11:495... there's a sound to have more relevance than the actual position.
Also to be more consistent with spacing.
00:14:109 (1,2,3) - vs 00:14:791 (5,6) - you are making a lot of complex patterns where these 2, put together, would confuse very much since one is a triple and one is a double. You should make the triple a 3/4 reverse slider to compare different these two patterns
00:21:836 (2,3) - spacing is too long for a hard difficulty, you should be aware that you're mapping for a 3* and cooking these patterns with a close distance between one note and another it would be very missable. For find a compromise with this you could remove a reverse on them and make them like triple, so the spacing would make more sense
same as 01:23:654 (4,5,6) - 01:25:018 (1,2) - 01:25:927 (5,6,7) -
Personally this is fine 00:31:382 (1,2,3,4) - , but I believe that you can polish this pattern more mostly because you didn't use this types of overlaps in no other place.
While it's fine, it feels a bit out of place in the rest of the diff. Here's an alternative execution https://setogay.s-ul.eu/mURIrGrd
Updated as suggested, was trying to be similar to 00:16:836 (1,2,3,4) - but I like your visuals better here :D
00:45:927 (1,2,3) - I don't think this is appropriate for Hard difficulty; the sliders for 1 and 2 would hide the circle for 3. It would be good to move the hit circle itself so that it is a bit more visible.
01:20:472 (5,6,7) - ^
00:58:882 (1) - 00:59:791 (1) - 01:00:700 (1) - etc The tick on the tail is pretty strong so you could map these sliders with 2 circles to represent that.
00:58:882 (1,2,3,1,2,3,1,2,3,1,2,3) - There is a distinct call-and-answer figure here where 00:58:882 (1,2,3) - is stronger than 00:59:791 (1,2,3) - . It would be cool if you could represent this by varying the spacing of these patterns.
00:59:791 (1,2,3,4) - 01:01:609 (1,2,3,4) - vs 00:58:882 (1,2,3,4) - 01:00:700 (1,2,3,4) - i would congratulate you for the idea, but these circles are still to close. Try to make sure they don't overlap with each other otherwise you cold make them similar to this spacing 00:49:563 (5,6,7) -
01:06:609 (4,1) - I feel like stacking here is a bit underwhelming to play, would be great if you did a full loop and continued moving. This means to start the pattern at the position of 01:06:609 (4) instead
leaving this as is but reopen this if i'm misunderstanding, the whistles/emphasis on 01:09:109 (2,4) - match similar parts in the kiai like 01:10:927 (2,3,4) - 01:14:563 (2,3,4) - 01:16:382 (2,3,4,5) - etc. so I think it's already consistent now
01:17:291 - You should probably keep the rhythm gap here 1/2 and map both as doubles 01:16:836 (4,5,6) - . The visual and spacing of 01:17:177 (6,1) - don't queue the player well enough to understand the 3/4 gap you did here.
See your point but will leave this one as is for now, there's other 3/4 gaps like 00:58:882 (1,2,3,4) and 00:36:836 (4,5,1) so I don't think this will catch players off-guard enough to have only this non-vocal sound clickable in the kiai
01:25:018 (1,2,3,4,5) - The grouping here needs a little bit of improvement. There's a major guitar change on 01:25:700 - that you're currently missing. There's a couple rhythm choices, I'll give you one example https://setogay.s-ul.eu/jXHAgJD3
