[General]
You have a spread issue between your Normal and Hard. Due to the BPM, the rhythm density of your normal right now is too heavy to function appropriately. Essentially, the solution is to make the Normal difficulty consist of more clickable objects, since right now it is slider heavy (I touch on that in my mods of the difficulties themselves) and very dense. You could put in an advanced, but honestly it'd be pointless and more productive to just fix the Normal.

As a general issue, your difficulty is extremely slider heavy. 00:00:022 (1,2,1,2,3,4,1,2) - is six seconds straight of playing sliders with 1/1 gaps. This is extremely straining on newbies, as they haven't properly grasped slider mechanics and also violates a guideline of the SRC. Most of this diff is like this as well. To solve this, you'll either need to incorporate more 2/1 timeline gaps or use more circles in between these chains of sliders. Circles/breaks every three seconds or so could work out nicely here.
00:06:567 (3,4,1) - 00:13:113 (3,4,1) - These 3/1 gaps really don't fit. Overall intensity did drop a bit, so a reduction of rhythm density makes sense, as does the lack of sliders, but here you're skipping beats that are part of what you're following strictly for simplicity when it isn't necessary. Mapping 00:06:976 - 00:07:794 - with circles would make quite a bit of sense here, especially when you've conditioned the player to click every 3/1, which just makes the 3/2 gaps feel more natural (they aren't problems when the song calls for them).
00:18:022 (1,2) - Unlike the previous sections where you have 3/1, the guitar is doing continuous 1/2 here, which indicates higher intensity. Similar to the above suggestion, I suggest changing 00:18:022 (1) - 00:18:840 (2) - to 3/2 sliders. The drawback is that it takes away from your emphasis with 00:19:658 (3,4) - though, but I think a total of 4 3/2 sliders overall fit better here.
00:27:840 (1,2,3) - This is uncomfortable and hard to read for players at this skill level, since you have even distance between the tail of 1,2,3 and 3 is also between 2 and 3. 3/2 gaps are a bit harder to read than 1/1 gaps already, but this makes it really confusing. A suggestion would be to increase the visual distance between 00:27:840 (1,3) but that wouldn't solve the harsh movement between 00:27:840 (1,2).
00:36:840 (4) - I don't think this measure is the same as 00:40:931 (5) since there is a skipped vocal on 00:37:249

These difficulty settings are all sorts of whack. For this BPM as well as the rhythm density, this AR is really low. I'll recommend AR 5.6 to fit with the rest of the spread's edgy settings. Adjust the rest of your difficulty settings to be at least 1 level below this AR (OD 4.6, HP 4.6 for example).
The DS you are using both violates the guideline on DS for normal difficulties and creates a terrible aesthetic. Distance between objects is almost twice as large as the speed of sliders, which leads to unintuitive slowdowns when playing a slider. With these things in mind, I recommend a DS of 1.1x
00:13:113 (4) - This worked really well earlier, but this vocal pattern only consists of 3 strong 3/2 beats as opposed to 4. I recommend shortening this repeat and leaving the timeline gap, though you'll have to move some stuff around to accommodate this.
00:04:931 (1) - You've got a long chain of objects here, which clutters up the screen. Not only that, but its also a chain of sliders which as i explained to Bergy, are hard to keep up with as beginners. I recommend changing this to a circle to break up this long chain of notes and provide some rest for the player.
00:31:113 (1,2,1,2,3,4,5) - Similar to the above but you're going to have to break it up even more. Based on how the intensity changes, I'd recommend changing 00:31:113 (1,2) - to a 3/2 slider and changing 00:32:340 (2,4) - into circles.
00:40:112 (3,4,5,6) - Most of the kiai rhythms followed vocals, so switching to drums like this doesn't really make much sense. I recommend mapping the vocals here with circles 3/2 apart than trying to follow the drums.
00:48:294 (2,3) - The 1/2 sliders don't really work too well here, since they don't serve to represent held sounds or merge rhythms together. I'd switch to 1/1 circles here.
00:49:931 (2) - Similar to the above, a 1/1 circle would work better here since this isn't mapped to a hold.
00:51:567 (1) - I suggest two 1/2 sliders here though, since they would represent the guitar here quite well compared to this repeat.
00:56:885 (2) - That 3/4 repeat slider builds up so nicely but it leads into a 1/1 slider, which is quite lame considering it skips a strong beat and this is a normal diff. I suggest using a 1/2 slider into a circle here.
01:03:840 (3) - This slider lands on nothing important. I'd shorten it to 01:04:249 where there's at least a strong guitar sound (which is what the head of this is following anyways). Additionally, I recommend a circle on 01:04:521, since it fits quite well.
01:13:658 (1,2,3,4,1,2,3,4,1) - Another chain of objects. I recommend changing 01:14:476 (3) - 01:15:294 (1) - and 01:16:521 (4) - into circles. Note that this introduces a 1/2 circle into a slider head. This is still difficulty appropriate even if it is this BPM, as it also does it into a slider head, and is less stressful than this massive chain of sliders.
01:21:021 (2) - Since you're mapping vocals, I think a 3/2 slider is more accurate here.
There are more chains of objects but i'm not pointing all of them out. Basically stay on the look out for chains of objects longer than 3-4 without 1/1 gaps in between them, especially those with sliders. Incorporating a few more circles with 1/2 gaps after them would also allow you to represent more intense sections better without compromising the difficulty, but due to the BPM i don't suggest anything more than 1 into a sliderhead.

00:16:385 (1,2) - According to 00:14:749 (1), this should be a 1/2 slider.
00:18:022 (1,2,3,4,5,1,2,3,4) - Honestly I think these two measures should be consistent since you're mapping the guitar, but it looks like you make 00:18:840 (1) - a slider because you don't want too many 1/2 circles in a row. In this case, I recommend you either make 00:18:022 (1,2) - a 1/2 slider or use this rhythm for both measures.
00:46:658 (3,4,5,6) - I don't like the idea of having 1/2 stacks and 1/4 stacks in the same combo, let alone this close on the timeline. I suggest unstacking 3 and 4.
01:17:203 (2,3,1) - Obscuring the position of 1 like this is likely too hard to read for players at this level. I recommend ctrl+g on 3 and creating a triangle between the ends of 2 and 3 with the sliderhead of 1. You'll have to move stuff around.
01:20:476 (5,6,1) - As above but with different visual arrangements.
[Insane]
00:00:840 (1,2) - For this difficulty this seems like a weak rhythm. Everything is equal in intensity here aside from 00:01:249 , yet so many beats are passive. I'd recommend using a more circle heavy rhythm, something like this.
00:14:749 (1) - 00:16:385 - Currently this slider skips the red tick of the rhythm you're following here (guitar). It doesn't really make much sense for this to be a 1/1 slider, so try a 1/2 slider + 1circle rhythm here.
00:33:567 (1,2,3,4,5) - 00:59:749 (1,2,3,4,5,6) - 01:37:385 (1,2,3,4,5,6) - I'd recommend ctrl+g on this rhythm, since the drums start on snares then switch to toms after 00:33:840.
00:55:658 (1,2) - You already introduced 3/4 rhythms in this section, so it doesn't make sense to use such a tame rhythm here. Try changing these to circles.
01:44:749 (1) - Feels weak that in this section you don't use a more intense rhythm, since the drums are going nuts here. At the very least, try out 1/2 slider + circle rhythms for these, but overall try to use a more intense rhythm.
Stopping here. Good luck!
