37.906, 39.060 etc etc. Given the absolute craziness of what you have later, I'd highly recommend stepping the hi-hat 16ths here and everywhere else in this section starting 30.637 to level off the difficulty curve a bit more smoothly
45.406 For the same reason, starting in this section, the hi-hats trap plays occasional 32nds at places like 46.156, 46.272 etc. which should definitley be charted with how difficult the jacks are later on.
In fact, you could even go for heavier layering in this section if you really wanted to design the best player experience (smoother curve).
60.406, 65.945 It's places like these that will drive the difficulty of this file, and not in a good way. 6-note split jumpjacks, even at this bpm will easily lead to a gigantic spike with the rest of what you have in this file right now. It's very reminiscent of powerpoints, actually, and the player reception to that file is a good hint for how people will think about this one if it were to in-game in its current state.
63.060, 68.599, etc. Missing a 16th to the synth after a clap in here and other places
67.791, 68.714 This representation for these instances where the synth clips and repeats feels a little bit limp as straight 16ths to me. In fact, they're very close to what you have jumpjacks and split jumpjacks to, just softer. I personally feel like 16th minijacks (not longjacks) would go a lot better in these places
102.406 missing, for vocals

This is a generally well-made file that is pretty brutal to the player. I'd be okay with accepting it wholesale if there were no real additional opportunities outside of the jumpjack section to beef it up, but there really are, and they're not just "hmmmm" instances, they're extremely audible and provide really interesting ways to enliven the chart as well (e.g. the 32nds at 45.406 section onwards).
I would also like to see some kind of nerfing to the long jumpjacks. I thiiiiiink you may be able to get away with making them all one-handed instead of split, although it'd still be quite the spike
More realistically you could also simply break the long jumpjacks into minijacks (e.g. [34][34][12][12][34][34] or...I guess [14][14][23][23][14][14] wouldn't be *too* bad either).

I think either of those options for making the jack section easier + taking some of the other suggestions to level off the difficulty curve is enough to move this out of CQ, as again, it's a good file outside the ginormous spikes. If player experience matters to you, then it's definitely something to consider in terms of how to make a more enjoyable file - sacrificing some strict technicality to level off the curve slightly.
I'm not the biggest stickler for a S M O O T H D I F F I C U L T Y C U R V E - honestly feel like I'm more lenient than the general meta on this - but in this situation, with easily available and sensible options to make the curve more reasonable, I think you should definitely consider the possibilities (both by making other sections harder, and by nerfing the jumpjacks easier). This file would have been fine to accept outright if there weren’t other files like these in the difficulty range it’s targeted at, but there are already a number of these one-spike-from-long-jack memes in the 70s-low 80s in the game, and I’d much rather see this file become a popular one instead of like those.

CQ: Level off the difficulty curve a bit for a better player experience – definitely do something to break up six-note long split jumpjacks. Additionally, consider layering harder in the first half, and including the 32nd trap hi-hats.
