Alright now that i'm done with my exams, i can finally get back to modding 
Bold: Unrankable/must fix.
Red: You should fix it, but it's up to you.
Italic: Suggestion. Feel free to ignore this if you don't like it.
Blue: Comment. Just putting this for fun
[General]
the combo colors should be the same for 1 mapset. 2 diffs have 5 and the rest have 4.You taught me that Sapphi ><
Add vocaloid3 in the tags. that's the engine IA is in, and maybe add Lia in the tags since she's the voice provider for IA.
Since you have a video, remove the letterbox during breaks. the letterbox will get in the way when the video is playing during gameplay.
I Agree with Niva, the offset should be at 12933(+5).
The kiai times on your diffs(Easy and Rin) are inconsistent. make sure that they're the same.
[Easy]
Maybe increase the HP by 1? you know to put a bit of pressure on beginners since the HP bar slightly decreases.
00:13:900 (1) - add a clap here? it sounds empty without and it'll represent the introduction of the song as it goes well with the instrumental.
00:18:094 (3) - replace the clap for a soft default finish, or add a soft default finish with the clap to match the cymbals in the song, or you can add the custom finish with the clap.
00:25:836 (3,4,5) - to make i easier for beginners, either replace it for a 2/1 slider or a 1/1 repeat slider. with a BPM this high, i don't beginners would hit at the right time.
00:28:416 (2) - the whistle should be at the end, not at the repeat arrow. adding the whistle at the repeat ruins the consistency in whistles.
00:34:223 (4) - add a clap at the end to match the drums.
00:39:384 (4) - you forgot to add a whistle at the end. add it for consistency purposes.
00:43:900 (1,2) - remove the NC for (1). the lyrics are still going from the slider. (2) should be a NC because of new lyrics.
00:49:707 (1) - add a whistle to match the vocals like you did on (2)?
00:52:282 - Do you have a reason why this line is unsnapped? if not, re-snap it back to (5).
00:55:508 (1) - add a finish here to match the vocals and to represent that the kiai is starting.
00:56:798 (3) - move the whistle at the end from the repeat arrow. same reason as 00:39:384.
01:01:960 (3) - ^
01:05:508 (1,2) - replace this for a 2/1 slider. it'll follow the vocals a lot accurate and beginners might hit (2) too early due to the vocals.
01:15:831 - maybe add a 1/1 slider to follow the guitar, or you can add a circle at 01:16:153 with a finish to show that the kiai is done?
01:30:992 (4) - add a clap at both ends to match the drums?
01:31:637 (1) - add a finish at the beginning, but reduce the volume to 40% to match the vocals. well since you have a timing point that has 40% remove the green line here because it's useless.
01:41:960 (1) - same as 01:30:992 but just the beginning.
01:45:831 (1,2) - same as 00:43:900.
01:51:637 (2) - same as 01:41:960.
01:54:218 (1) - remove the NC for consistency at 00:51:637.
02:07:444 (1,2) - same as 01:05:508.
02:41:960 - if you do this, you have to remove (1). add a 2/1 slider or a 1/1 repeat slider to follow the vocals.
02:52:605 (1,2) - same as 01:05:508.
03:10:321 - you should add a 1/1 slider or a circle at 03:10:643 to end the song? it'll look weird and not exciting for players if you ask me.
[SG's Normal]
Increase the HP and OR by 1. it'll flow a lot smoother to the song during gameplay.
00:14:218 (1) - for consistency purposes on easy, remove the NC on this note.
00:24:218 - maybe add a circle, or remove (4) and add a 1/1 slider to follow vocals accurately?
00:27:121 (1) - replace the finish for a whistle. i don't hear anything climatic coming up like the cymbals, or the rise in vocals.
00:28:734 (2) - replace the whistle for a clap. yes it matches in vocals, but it ruins the consistency in claps
00:29:702 (1,2,3,4) - switch the hitsounds for (1,3). if you want to keep the consistency, you should do this. it'll sound a lot nicer during gameplay. i also felt a bit uncomfortable when i hit (1,3). it sounds weird IMO.
00:37:444 (1,2,3) - similar as above, but same as 00:27:121, and replace the whistle for a clap on (2) to match the drums. the whistle doesn't fit with the part at all.
00:52:282 (4) - add a finish at the beginning. it goes well with that sound IMO.
01:05:508 - you should add a circle just to make sure that players don't hit the next note too early due to vocals, or remove (1) and replace it for a 1/1 slider.
01:09:702 (3,4) - add finishes on these notes to match the cymbals in the song.
01:15:831 - same as easy.
01:27:766 (3) - the clap should be at the end, not at the repeat arrow. it sounds bad and it ruins the consistency in claps.
01:34:863 (2) - you can do 2 things: replace the whistle for a clap since you have a clap on the repeat arrow of (3), or add a clap with the whistle since you have a clap at the repeat arrow, and a whistle at the end of (3).
01:41:960 (1) - similar as above. add a finish with the clap to match the cymbals or replace the clap for a finish. same reason.
01:52:282 (1) - i don't remember you doing this at the 1st part before the kiai. make this repeat once and add a circle. with the 1/1 slider in effect and where that note is, players might get "too" nervous and might let go at the 2nd repeat.
02:07:444 - same as 01:05:508.
02:18:089 - hmm in this case, add a circle here with a finish. the 1/1 slider would look bad if it's following the drums. anyways my reason is that it'll match the cymbals.
02:22:040 - *nazi* move the break back to the white tick. that's where the drums start.
02:32:927 (5,6) - to follow the vocals a lot smoother, replace this for a 1/1 slider. it'll fit with the long pause in vocals.
02:41:960 - similar as easy, but the circle isn't there, and same suggestions as easy.
03:10:321 - maybe you can add a circle to follow the drums?
[Gu's Hard]
You should do OD6. it should give a bit of a challenge for players.
00:14:863 (1,2,3,1,2,3,1,2) - Make sure that the repeat arrows are fully visible. the hitburst is covering the repeat arrows and that's a no no.
00:18:895 (6,7,8,9,10,11) - orz going all out on this o.o? myabe you can replace this for a kick slide to make it easier since it's a hard diff?
00:24:540 (1) - *nazi* stack this note perfectly on (4). it looks weird when i don't see a perfectly stacked note during gameplay.
00:25:831 (1) - *nazi* make this slider symmetrical. it'll look nicer if you ask me.
00:38:734 (1) - try this instead: remove all repeats, add a circle at 00:39:218 and another 1/1 slider starting at 00:39:379. i think it'll look fun for players to play that kind of pattern.
00:52:927 (1,2,3,4) - Do Ctrl+R for (2,4). it'll flow a lot smoother and the pattern looks fun to me. personally i like doing patterns like these, but i don't like patterns like these. it ruins the fun for me. anyways it's up to you if you want to do it.
00:54:863 - i feel that a note is missing here. add a note to follow the vocals in the song.
01:15:508 (1) - maybe add a repeat and add a finish at the end to match the cymbals?
01:30:992 (1,2) - remove the NC for (1). the vocals are still going from the previous slider. (2) should be a NC because of new lyrics.
01:35:186 - add a circle to follow vocals?
01:36:153 - ^
02:11:637 (1) - with the slow down in effect, this slider might throw off players because the sliderlength looks the same and they might think that the slider is at its original speed. in other words this slowdown might surprise players. put it back to its original speed so that it'd be less confusing.
02:41:960 - same as normal.
02:52:927 - same as 01:35:186.
03:10:643 - either add a repeat or a circle with a finish to represent that this is the end of the song.
[Rin]
Increase the HP by 1. Kanon's diff has HP7 so why not do it here?
00:18:250 (7) - Make this a NC. you should keep it consistent with the other diffs at the beginning since i find it odd that this combo has 11 notes and the rest has 6-7.
00:23:895 - add a slider with a slowdown to represent the introduction of the song.
00:53:250 (1,1,1,1) - add claps at both ends except for the end of (1). add it at the beginning only. it fits with the drums in the song IMO. to make it more effective, gradually increase the volume for every clap.
01:02:444 (4) - align this note with (3). since you did it on the left side, so i don't see a reason why this circle is spaced out like this.
01:12:766 (4) - ^ but at the right side.
01:15:831 - same as easy.
01:52:282 (1,2,3,4,5) - same as 00:50:347.
01:54:863 (1,1,1,1,1,1) - same as 00:53:250/
02:00:508 (3,4,5,6,7) - ik that you can make this triangle nicer. just notes some notes around to make it nicer. something like this should work. just move (6) a bit to the right.
02:17:605 - either add a kick slider or a stream to follow the drums?
02:28:089 (1,2,3,4) - 1/8 sliders right?
02:30:427 - maybe add a stream to follow the guitar riff? if not a kick slider but at the red tick.
02:33:895 (2) - maybe Ctrl+R for a smoother flow?
02:34:540 (2) - ^
02:35:185 (2) - ^
03:05:863 (3,4) - the spacing on these notes should be equal like (1,2). it looks weird during gameplay that the notes are clumped up together as the BPM decreases.
03:10:321 - for this one, i suggest a 1/2 slider and a circle. if you ignore this, then you can come up with something else.
[dksslqj Style]
00:14:863 (7) - make this a NC. the instrumental changes from here.
00:16:153 (4) - I think this should be a NC. same reason as above.
00:23:895 - add circles at the white ticks to follow vocals.
00:43:895 (1,2,3) - Ctrl+R (1,3). it'll flow a lot smoother during gameplay.
00:51:637 - add a circle to follow vocals.
01:51:637 (3) - re-snap the end of this slider. it's unsnapped atm.
02:41:960-02:43:573 - besides that circle, i suggest that you add notes to follow the vocals.
02:47:605 - add a circle to follow vocals?
03:06:135 (10) - the spacing suddenly changes from this note. try to make it the same and consistent for this combo.
[0108]
same comment about the HP drain on Rin's diff.
00:14:863 (7) - same as Kanon's diff.
00:16:153 (3) - ^
00:17:444 (4) - ^
00:23:895 - same as Rin's diff.
01:15:831 (2) - ik you can make a wave slider nicer than this. make it nicer and make it look smoother.
01:25:831 - same as 00:23:895.
01:49:379 (2) - *nazi* the gap between (1,3) is uneven. move it around so that the spacing for this is even.
01:52:927 (3,4) - switch spots for these notes. the pattern would make sense if you do so.
02:41:960 - maybe add notes at the white ticks to match the vocals?
02:42:605 (1) - *nazi* i was expecting this note to be stacked at (6). it'd look too crowded if it's at the middle like this. so stack this on (6) to make it easier.
OMG I'M DONE
. 1st time modding 6 diffs in 1 mapset. anyways Star and GL
