00:01:307 (1,2,3,1) - Rhythm here doesn't make too much sense. It's a calm section, so this would normally be appropriate, but since you started off with such high rhythm density at 00:00:450 (1,2,3,4,5,6,7), it confuses what kind of feeling you're going for. I assume that for an intro section, you'd want to start out relatively low intensity, or if not, at least make it clear that you aren't lowering it.
00:07:735 (1,2,3,4) - From here on out up to the first bookmark, I can't really tell what you're following. Rhythms for this song are fairly consistent, so why aren't the notes you map consistent with it? It looks like quite a few variations here and it ties into the above point for intensity purposes, but also that this rhythm is unclear as to what you're following now.
00:14:807 (2,3,4,5,6,7) - Intensity increases, why are less clickable streams starting to become present?
00:35:592 (4,5,6,7,1,2) - A pattern like this without any sort of other prior patterns is very difficult to read, more so for players of your target audience. You should introduce some sort of less intense version of this pattern earlier on.
01:12:450 (1,2,3,4) - Spacing is pretty high for this section. I actually don't think I see you use a spacing of this level even at kiai time, but considering before you were using overlapping streams, maybe consider doing that here so that your higher spacing has more impact in other sections?
01:45:878 (1,2) - Intentional or not, this overlap does look pretty weird, with the slider head of 2 overlapping with the slider track of 1.
01:53:592 (1,2) - It'd be cooler if you rotated 2 a bit to form a curve with 1 (move 01:54:878 (1) - to keep your blanket and prevent overlap):
https://halfslashed.s-ul.eu/GK96EHQB03:20:592 (1) - How about a spiral or a loop instead for this sound?
https://halfslashed.s-ul.eu/nqdFVzre 04:54:450 (3,4,5,6,1,2,3,4,1) - First split stream almost 5 minutes into this map. Again, very difficult to hit for your target audience, and this is the first occurance. You had many other chances to introduce this earlier, so why is this coming in now?
04:58:735 (1,2) - Not a fan that you're completely ignoring the 1/3 here. I'd even be "ok" with repeats if you didn't want to make it too hard, but you just skip them completely..
06:55:579 - I can't hear what these spinners are for. I don't hear a held sound, nor an increasing/decreasing sound, nothing. All of the beats are skipped to the point where this section is just filler. If you're going to map this, using some sliders to emphasize the strongest beats of the melody (similar to mapping an Easy) would work.
I'll stop with this. For most of the map (I gave a couple examples), rhythm is a major issue. from section to section, rhythm seems to be switching back and forth on low and high densities. This makes it very difficult to tell what you are trying to follow and detracts from what you want to emphasize when following things. I couldn't really focus on your spacing since I couldn't tell what you were doing with the rhythm for most of the map. Finally, one of the things that disappointed me personally is that you had some really cool patterns that you could've evolved and made something cool with, starting off with 00:00:664 (2,3,4,5,6,7,1) , and later on with 03:54:021 (2,3,4), which could've been turned into some larger spacing varients, but since you didn't seem to do anything with this, they look out of place.
