00:26:650 (1,2) - i dont think you should space these 1/2 objects like 1/4 due to how 00:11:240 (2,3) - is introduced, people would easily misunderstand it as the same from the latter.
just space them out and not overlap them.
00:45:339 (1) - 00:45:666 (1) - you dont need to nc here, it's getting repetitive seeing how 00:44:847 (1) - this combo is only a single combo. the next nc could just be here instead 00:46:322 (1) - since this is where the next musical section starts
00:45:626 (1,2,3) - you shouldn't probably stack these like they're a triple since people would misread either this pattern by playing it as a triple or the following which could be possibly 01:01:856 (4,5,1) - 01:08:741 (2,3,4) - etc. by playing it as 1/2 since they saw the former pattern. players of this level barely know how to read approach circles or any other technique to read these.
it'd be better to just unstack and separate these to a normal spacing that you use for 1/2 rhythms.
great point, i'll just unstack these as you suggested
EDIT: REARRANGING IS A BIT MESSED UP SO I CHANGED RHYTHM INSTEAD
00:45:339 (3,4) - is now 1/2 beat slider because snaredrum is the sound at sliderstart, the circles belong to kickdrum now (since it's 2 circles stacked it can't be confused as a triple right...?)
01:00:257 (1,2,3) - why not overlap this pattern with the same as 00:57:634 (1,2,3) - and 00:58:945 (1,2,3) - ? I think you're trying to emphasize each vocal phrase from the previous 2 patterns but i think you could overlap them as well but with a higher spacing to give that "specific" emphasis for these vocals since it's quite a special spacing and unique to this particular section.
additionally, you could also space this 00:58:945 (1,2,3) - to a more larger spacing than 00:57:634 (1,2,3) - but lesser than 01:00:257 (1,2,3) - for a more specific emphasis to each vocal phrase like how you also change each slidershape in 00:56:814 (1,2) - and 00:58:125 (1,2) -
kinda was expecting a ctrl + g (for change) red anchor slider at 01:00:748 (1) like 00:57:634 (1,2,3,1,1,2,3,1) :<
01:06:650 (1) - i dont think ncing here would be efficient if it's just to emphasize vocals i think, it'd be much better if you'd instead follow the musical section and leave the nc on 01:07:306 (1) - and remove on 01:06:650 (1) - since it's getting repetitive
01:13:863 (4) - rhythm for this reverse slider is quite bland and could be improved for a hard diff since it's also too simple imo. current rhythm is bland because it's only mapping the drums that are on the white tick, while a hard is usually almost composed of mostly 1/2 and occasional 1/1, 1/4 rhythms, this could be denser by following different instruments present in the background.
i suggest following the guitar that also happens to map the red ticks on 01:14:027 - and 01:14:355 - you could do 1/2 slider, circle, 1/2 slider https://i.imgur.com/l7f0ZQ9.png to effectively both follow the guitar and still emphasize the snares on the drums.
01:21:732 (1,2,3,4,1) - personally, i just find these overlaps too dirty. you have a lot of space to put these objects but you just clump them together in this tiny space.
if you want to keep the circular motion, you could instead try having it as a perfect equidistant triangle instead of an imperfect one, having each object rotated 120 degrees then overlapping the 4th slider to the one nearest to 01:23:043 (1) -
https://i.imgur.com/1QkQUOa.jpg or something similar
01:26:158 (2,4) - shouldn't these circles be closer to their previous objects, not the other way around? 01:26:322 (3) - and 01:26:978 (1) - are quite louder and could be emphasized by having the jump there instead of the weaker circles.
do it like this maybe https://i.imgur.com/E1V2II7.jpg
01:35:175 (1,2,3,4,5,6,1) - how you handled the increasing spacing pattern here could be improved imo. i think you're trying to map the pattern to the percussion making it more spaced as the drums get louder, but since there are vocals i think they should be properly emphasized too.
imo 01:35:502 (3) - is where the larger spacing should start since it's where the vocal is the most powerful. as it is now, the vocal is on the lower spacing which is contrary to what the pattern is doing.
i suggest https://i.imgur.com/F7N4grn.jpg this pattern placement to emphasize vocal effectively.
