00:29:786 (4) - Consider a nc here? It's quite separate from this pattern before 00:29:036 (1,2,3) -
00:25:786 (5,6,7) - Here as well.
00:35:036 (1,2) - I think it'd be cool to have this stacked like 00:34:536 (3,4) -.
00:16:036 (1,2,3,4) - There isn't a drum on 2.
00:45:036 (1,2) - Make these the same slider?
I have some major concerns about your rhythms and spacings in this section. Honestly though almost all of the problem I have with this map are just rooted in these issues. They're consistent throughout the map, and I understand they may not align with what you have in mind with the map, but I do heavily suggest you consider these issues. While the time stamps are of the earlier ones, make sure you go through the entire map and apply these changes if you choose to.
00:16:286 (1,2,3,4,5,6,7,8,9) - If this is mapped to the drum roll, 00:16:348 (2,6) - and 00:16:848 - this repeat, these notes are overmapped. There's not much of a point in over mapping these rhythms either. They're sets of triples musically, and mapping this as one continuous stream really betrays the music here. You have a lot of streams that are overmapped like this.
00:24:036 (1,2,3,4,5,6,7,8,9,10) - Is another example.
00:28:536 (1,2,3,4,5,6) - Some of your triples are also overmapped extensively.
I'd heavily suggest you go through and remove these instances of overmapping. The song is interesting enough already, so it doesn't really make any sense to overmap additional rhythms that simply do not exist in the song.
00:17:161 (2) - Kicksliders like these aren't mapped to any sound on the tail, and they don't really seem to have any other purpose, since you often use single circles to map the same sounds. All they seem to do is give a false sense of higher spacing between these kicksliders and the following objects.
Other examples include 00:19:161 (2,3) - , and 00:23:161 (2,3) -
00:23:536 (4,5,6,7) - This is another example of extra kicksliders being added, the drums don't begin until 00:23:786 (6,7) - , but by choosing to map 00:23:536 (4,5) - you lose the emphasis that making 00:23:786 (6,7) - kicksliders gives.
00:53:786 (4,5,6) - Other times the usage of kicksliders seems random and not really mapped to anything.
00:51:786 (1,2,3,4,5,6,7,8,9,10,11,12) - While I do understand you're trying to map the growls here, these really don't work that well.
00:52:286 (5,6) - the vocal here changes, but it's mapped the same way as the previous repeated vocal ticks, so It doesn't really make any sense. I'd recommend that you separate and distinguish 5 and 6.
00:17:786 (6) - This slider and those like it fail to convey the rhythm of the guitar, 00:17:911 - This is a major note and would be much better mapped as a clickable object. It's inconsistent with other parts such as 00:21:911 (6,1) - where you do map it as a clickable.
01:15:036 (1) - I'm not really a fan of skipping this red tick drum here, it feels quite rhythmically empty, especially since the guitar that would be sustained should start on 01:14:911 - which isn't even mapped.
01:15:536 (3,4) - and 01:19:536 (4,5) - Spacings like this don't really fit either, they're just simply too low for the kick and downbeat to feel like they have any emphasis.
02:36:411 (4,5,6,7,8,9,10,1,2,3,4,5,6,7,8,9,10) - Could you scale the spacing here slightly higher to avoid the overlap between the stack and the single notes?
03:11:286 (3) - I don't see a reason to skip the 1/2 rhythm here i'd recommend changing this to a 1/2 slider or keeping the 1/2 singles.
03:20:411 - 03:20:911 - are some other timestamps of the same issue. If you want to keep passive breaks you can just use repeat sliders to map them and not skip.
