Hi miikyuu, mod request from my modding queue here :3
[General]
I'd use the same combo colours to all diffs
[Level 1]
00:38:086 (3) - Finish here would would emphasize the cymbals in the song
00:39:801 (1) - ^
00:41:515 (2) - ^
00:47:086 (3) - ^
01:31:229 (1) - ^
01:38:086 (3) - ^
02:10:658 (3) - ^ on repeat too
02:35:944 (3) - I'd move this slider 2/2 later using new combo and removing it from 02:37:229 (1):

03:16:658 (4) - New combo
03:39:801 (1) - This spinner should end on 03:41:301 because it's following the vocal
Fine map, some suggestions about hitsonds
[Level 3]
Add the same finishes I suggested you above if you liked it :3
00:49:229 (4) - New combo?
01:05:515 (3) - Reduce this slider by 1/2 to fit the vocal like you did for 01:04:658 (2)
01:10:658 (5) - New combo
01:38:086 (5) - ^
01:56:086 (4) - ^
02:03:801 (3) - Same of 01:05:515 (3)
02:08:944 (1) - Mh I don't like this slider's shape D: What about to make something like this? I think it'd flow better
03:35:944 (4) - x:440 y:240 to have a better blanket
03:41:515 (1,2) - These 2 circles should be moved 1/4 earlier to fit the vocal
[Level 6]
I think this AR is too low. Increase it by 1
About hitsounds the same of Level 1 diff ;3
00:15:586 (1) - You are following the vocal's rhythm so remove new combo here and add it on 00:14:729 (4)
00:43:229 (1,2) - ^
01:23:836 Since the 01:23:944 (5) should be snapped 1/4 earlier to fit the vocal sound what about to add a circle to make a triple here?
01:52:872 (5) - New combo
02:31:229 (3) - Improve this curve to have a better blanket here (in the code I have fixed the next slider too):
[Saten]
02:09:801 (1,2,3,4) - This pattern with these jumps is really confusing to play. At least I got this problem test playing the map.
03:01:229 (3,4) - If you see these 2 sliders in test mode the (4) isn't overlapped as it should with (3)'s end
03:03:747 (2) - You can avoid this circle, really. Remove it
03:07:872 (3) - Reduce this slider by 1/2? It should end on the long white tick 03:08:086
Crazy map s:
[Origin]
00:37:658 (5) - Remove a repeat from here
01:44:301 (4) - Make this blanket more flowing, it's ugly
02:34:658 (1) - You should use this rhythm instead, you actual one doesn't fit the song:

02:36:372 (1) - Reduce this slider by 1/2 and add a circle on 02:36:694 to fill the empty. The rhythm flows better
03:05:836 (2) - Same of 01:44:301 (4)
03:19:229 (5) - New combo
[Nyaten]
BPM 280 AR 10? No, just no. It's impossible. Reduce it till 9 :\
00:27:586 (3) - Unreadable slider.
00:32:086 (3) - New combo to make it rankable
00:56:944 (1,2,3,4,5,6,7,8) - Why so huge jumps çç
00:58:658 (1,2,3,4,5,6,7,8) - ^
Overmapped ._.
That's it, good luck (:

02:46:229 (1,2,3,4,5) - Make this pattern symmetric:124,316,151229,2,0,B|68:248|124:144|224:176,1,220

SPOILER
02:53:515 (3,4,5) - I don't like this pattern because the asymmetric slider 02:53:515 (3) breaks the map's flow. I can suggest you something like this:328,220,166229,5,0
