Hmm...
General:
Add S_o_r_d_a and Mevius to tags? Mevius is Sorda's last known name.
Your difficulty names seem odd. You have easy/normal and then you have Shoot/HiNaTa. Can you make the names consistent? Like rename easy/normal if you want to keep Shoot/HiNaTa or rename Shoot/HiNaTa if you want to keep easy/normal names.
If you really want to keep the names, can you add like "Shoot is hard HiNaTa is insane" in the description?
Easy:
Looks good.
Normal:
00:13:026 (2) - Err...I don't like how this is overlapping with 00:11:749 (4) . Can you move the note somewhere else maybe?
00:50:898 (2,3,4,5,6) - Hmm..I think this might be confusing. You have stack notes and kick sliders in this bunch here. Perhaps you can make it slightly easier to read here?
Sorda:
Hmm maybe AR -1? Big jump from normal to hard.
Shoot:
Is this hard or insane?
Some combos are kinda long :/
00:43:239 (3) - Not a big deal, but maybe move it little lower? Kinda close to HP bar but it's still okay. Up to you to move it.
Little NC mod.If you follow this, follow it all
00:42:388 (1) - Remove NC
00:43:239 (3) - NC here.
00:44:728 (1) - Remove NC
00:44:941 (3) - NC here?
00:48:132 (8) - Remove slider. Add note here and 00:48:345.
00:48:345 (x) - NC here
Hinata:
01:09:196 (9) - Hmm. Don't really like the overlap. Think you can change it?
01:11:962 (7) - ^
I tried my best. :3 It's up to you to use it or not.
