Hi~ good to see this is still alive, have a mod as you requested from my queue.
[General]
AIMod says your kiai isn't snapped in all difficulties, and Oni has different preview time and tags than the rest of the diffs.
[Oni]
00:17:150 (87,89) - I suggest to swap the color of these two to make the stream a bit more friendly as it'd have even numbers for the colors?
00:25:857 (138) - Maybe this a big don as in the previous patterns to keep the consistency?
00:32:754 (174) - A bit kat here? like in the previous suggestion.
00:33:616 (181,182,183,184) - A
d ddd pattern would feel more natural here as drums are not that loud and allows the big kat in front have more emphasis imo.
00:43:961 (241) - Remove this so the finishers could be played better
01:12:323 (400,402) - As I said a bit above, swap color of these two?
01:21:030 (453) - A big don here, as I said a bit above too.
01:27:926 (493) - A big kat here :3
01:28:788 (500,501,502,503,504,505) - You could inverse the color of this part, same reason as I explained in previous one.
tbh I felt some double pattens (xx xx) a bit weird as the music doesn't have that rhythm (or maybe I couldn't catch it), they fit there though.
[Muzukashii]
00:08:961 (31) - I'd remove the finisher here, it sounds a bit off as then music doesn't have enough emphasis there.
00:25:857 (104,105,106,107,108,109,110) - I'd suggest a
k d dk d dk pattern here, it's a bit more friendly and easier to catch.
00:28:443 (115) - You could remove this note and make 00:28:271 (114) a don so this part follow the guitar and allows the next big kat note have more emphasis
00:31:374 (127,128,129,130,131,132,133) - Same as a bit above, a
K d dK d dK 00:37:581 (151,152,153) - This feels better being a
ddk, as the last note has more emphasis.
00:40:340 (161,163,163) - ^
00:43:098 (171,172,173) - ^
00:45:167 (179) - I'd remove the finisher here, the last pattern was much stronger, so this having a finisher feels a bit odd.
01:02:236 (246) - Maybe remove this one?
01:21:030 (329,330,331,332,333,334,335) - Same as I said above about a
k d dk d dk pattern
01:26:547 (346,347,348,349,350,351,352) -
K d dK d dK 01:32:236 (369) - Maybe remove this one to make the 1/2 pattern not too dense.
01:37:754 (392,398) - ^ But specially the last one so the finishers pattern feels stronger.
01:40:340 (403) - Remove the finisher here.
01:43:271 (414) - Maybe remove?
Nice
[Futsuu]
00:33:098 (74) - Make this slider end in 00:33:443, it'd be better if it just follows the trumpet-like.
00:43:788 (102,103,104,105,106) - I'd keep this part like in higher diffs, first 4 beats are stronger than the last so a
D D K K k would feel better.
01:28:271 (207) - Same as the first slider.
01:38:961 (234,235,236,237,238) - Same suggestion about the finishers.
01:45:857 (251) - This slider felt pretty random here, put some circles instead.
01:50:685 - Maybe use a slider/spinner from here until 01:51:374?
I also suggest you to make the 1/2 patterns of the same color, as they may be a bit hard to handle in this level, this would require adjust the color of other notes, it depends of your style
[Kantan]
00:13:961 (25) - Even if ocasional use of 1/2 in Kantan is allowed, this one may be a bit hard to handle as the rhythm is a bit "irregular", so I'd suggest you to remove this one.
00:19:478 (38) - ^
00:34:133 (60) - Maybe use a kat here?
00:43:788 (77,78,79,80,81) - As in the other difficulties, a
k d dk d dk would be more fitting here.
01:09:133 (125) - Remove.
01:13:271 (135) - ^
01:14:650 (139) - ^
01:29:305 (161) - Maybe a kat here?
01:38:961 (178,179,180,181,182) - You'd already know
01:50:685 - Maybe use a slider/spinner from here until 01:51:374?
Whoa all these red tick objects, I think it's fine as they're following the main rhythm, even if it's tricky.
That'd be all from my part, nice mapset overall, good luck :3
