Hi Trust, m4m as per your request.
[Easy]
00:09:326 - I feel like we miss a really important object here because this is the highest that the vocals get in this musical phrase, so I think it deserves some mapping. Adding a circle here would be fine I think.
00:11:326 (4,1) - switching these NCs would be more consistent I think.
a little bit of NC consistency modding here:
00:22:526 (1) - remove NC
00:24:126 (3) - NC
00:25:726 (1) - remove NC
00:38:526 (1) - For this spinner, I suggest either silencing the end or adding a whistle, not sure which I prefer more.
01:02:076 (2) - I would say remove the finish here, I know that you want a hit sound here, but I think a finish doesn't really match the music that well and actually sticks out a bit too much here. Maybe try a whistle?
01:03:576 (4) - remove finish here
01:04:326 (1) - add finish to the head of this one, makes more sense to me.
01:07:884 - Inconsistent kiai time, change this to 01:07:888 to match the other diffs.
01:11:826 (2) - NC here, fits the music nicely.
01:12:951 (3) - nazi thing, but (397,180) is as close to a stack as this is going to get.
[Normal]
00:18:926 (4,2) - not sure if you intended to offset these or not. I would suggest stacking them perfectly or finding an alternate way to map this part. The offset doesn't really look great I think.
01:00:388 (4,1) - switch NCs here to match 01:01:888 (1,2) and 01:03:388 (1,2).
01:12:388 (1,2,3,1,2) - I don't really like the super heavy vocal matching here. To me this seems more empty than the way you mapped Easy, so I would suggest to stick with mapping to the drums here instead. The drum beat is much more important I think at this stage, and I think it feels better to play the drums instead of all of these red tick sliders. Remapping this part will also give you the opportunity to use more hitsounding which will sound better.
[Hard]
AR7 fits better I think.
00:04:926 (1,3) - (3) to (247,41) for a perfect stack.
00:54:013 (1) - For this, I like for it to be a bit further to the right, and then copy paste, and ctrl+h+j it for 00:54:763 (1). I think this rotational symmetry matches really well with 00:53:076 (3,4) and also adds some little jumps that match the music nicely. If you do this, I would reshape the slider so that it blankets 00:53:076 (3).

http://puu.sh/5LZsU.jpg00:58:326 (1,2) - 2.0x jump seems a bit large for this diff, consider reducing this.
01:00:576 (6,7) - this seems also a bit too big for me. The sharp angle change also makes this a bit difficult.
01:00:763 (7) - I would actually prefer for this to be a 1/2 slider which would provide some mapping for the drum roll in the bg. Alternatively, you could also put a repeating 1/4 slider to match that.
01:06:763 (2) - same idea for this one. I know that you are playing around with the 1/1 spaces between objects for this part, but for this one and the previous one, it just feels empty to not have any object where there is a lot of stuff going on with the music, especially in your Hard. I think the other uses of those full stops work well, but for these ones I think mapping the music out more is better.
[Fiya's Insane]
AR8 is much better for this diff I think than 9. The bpm isn't too high, there isn't tons of overlaps which make readability hard on 8, and AR8 better suits the object density.
00:04:526 (11,12) - I don't really like this stack, i think a jump from (11) to (12) feels a lot better to play since you get that nice jump with the vocal, and I think it is more fitting with the way you mapped the rest of the diff.
00:06:326 (4) - remove the finish here, the bass drum is constant in this part and falls solely on white ticks, so having one that breaks the consistency sticks out.
00:09:526 (4) - same on this one
00:10:726 (9) - I think you can remove the finish here, doesn't particularly fit the music I think.
00:22:326 (6) - remove both of the finishes on this slider.
00:44:638 (3) - remove finish
00:48:388 (6) - remove finish
00:56:638 (3) - remove finish. I know that you want hitsounds for those parts, but I think a simple whistle is fine. For most of those sliders, the real bass drum is in the middle of them, so there's no reason to force a hitsound that doesn't match the music.
00:58:888 (2,3) - I really don't like this stack compared to the rest of how you map this part. I would like at least a little bit of spacing here. I think it matches the style of the kiai a lot better and it will make this part play more flow-ily (wat).
[Insane]
AR8, as with Fiya's.
00:13:526 (1,2,3) - I didn't really like this triplet. I don't really hear much in the music to match this, and it didn't feel that great to play since there was no music backing it up. I think a 1/2 slider fits better here, or just 2 circles with 1/2 spacing.
00:17:326 (5,6) - This stack isn't so great to me. When you're doing a jump pattern that leads into a strong vocal ending like the one here, it makes the most sense to provide the biggest jump to the slider that matches the last vocal of the pattern. The stack here kills the flow completely, and feels very anticlimactic compared to the rest of that pattern. I would make this a jump instead of a stack, which I think plays and feels better and makes more sense as a natural continuation of the jump pattern.
00:18:126 (3,4,5) - the spacing here feels too small considering the extremely strong emphasis of those finishes on these sliders. Consider upping the spacing here to match that musical idea.
00:19:526 (1,2,3,4,5,6) - I think the way that this is mapped sort of misses out on the uniqueness of this part compared to the previous parts in the stanza. here we miss out on some drum action. There are two triplets here, one at 00:19:726 and one at 00:20:326. I think it would be better for you to map this part keeping these triplets in mind.
00:22:326 (1,2,3,4) - I don't really agree with the SV decrease here, mainly because the backing music is remaining strong here. I don't think the vocals diminish enough here either to justify an SV drop, so I would say just keep the SV the same here as was before.
00:24:526 (2,3) - I would prefer a little more spacing here. Slider leniency makes it so that the jump really isn't as big as you think it is here, so this feels a little tight considering the emphasis on the vocal on (3).
00:27:126 (11,1) - space these out a bit more, this anti jump is too small imo.
00:32:126 (4,5) - stack is a bit off here.
00:35:326 (4) - NC here, matches the one you do at 00:28:926 (1).
00:51:388 (1,2) - a little more spacing between these ones I think to account for slider leniency.
01:02:263 (4) - I don't particularly like this slider because it puts the vocal at the slider end which feels weak and doesn't really match the rest of the diff. The way you map 01:03:763 (8,1) is better and I think is something you should do at this part as well.
01:08:169 (3) - This slider is really awkward and doesn't seem to be mapped to anything. I would say make a circle at 01:08:263 for consistency with 01:09:763 (6).
01:12:201 (2,3) - A little more space here, I think the vocal makes this part deserve a bit more spacing.
01:18:013 (2,1,2,1,2,1,2) - I like the pattern here, but to me, it makes sense to increase the spacing as the guitar crescendos. Don't know if you feel like reworking this, but I think it would match the music better with the spacing going up with the volume.
That's all from me, good luck!
