00:21:143 (13,14,15,16,17,18,19,20,21,22,23,24,25,26,27) - This structure isn't suitable to how you've mapped it - By that I mean that your mixed mapping doesn't fit totally to the song. Your structure at 00:28:088 (40,41,42,43,44,45,46,47,48,49,50,51,52) - was better, so why not applying it !
00:35:875 (71,72) - Invert them ? The latter note is higher-pitched and clearer.
00:36:506 (73) - , 00:39:031 (83,84,85) - Since the pitches in these parts are nearly as high, maybe use k on new syllables or portas. So 73 would be k, and 83-85 kdk.
00:55:657 (154) - To stay consistent with 00:48:817 (122,123) - , put a k before 154, and then change next note to d.
00:57:236 (160,161) - dk to keep consistency with 00:50:501 (129,130) -
00:59:656 (170) - k as your preceding don is on a beat, whereas the lyrics are clear, loud and pretty much acute enough to deserve a kat.
01:08:284 (200,201,202,203,204,205,206,207,208,209,210,211,212,213,214) - Try changing your structure to have some variety ?
01:19:228 (245) - Put this as a k, the vocal pitch is even higher than the following note.
01:24:068 (263,264,265) - Here, I recommend you to put kkk, to emphasize more on the lyrics, as you've done on 00:36:927 (74,75,76,77,78,79,80) - .
01:37:958 (317,318,319,320,321,322,323,324,325) - Might change how your pattern is ? Here it's getting quite monotonous.
01:49:743 (362,363,364,365,366,367,368) - Change this as well ?
01:51:426 (369,370,371,372,373,374,375) - ^
02:45:303 (64,65,66,67,68,69,70,71,72,73,74,75) - ^
02:29:414 (1) - This note lands on nothing, consider moving it, please. The red tick before is a suitable area.
00:53:763 (145,146,147,148,149,150) - Don't do 2-color 1/4s in Muzukashii please.
01:05:969 (190,191,192) - ^
01:39:220 (323,324,325) - ^
01:40:904 (330,331,332) - ^
01:48:270 (355,356,357) - ^
02:32:255 (13,14,15) - ^
02:33:939 (21,22,23) - ^
02:52:879 (96,97,98) - ^
[Oni]
I've went through the whole map, checked the spread and everything, and concluded that it's not really suitable as it is. The only solution that I can offer you is to end up remapping the chart. Many parts needs to be revamped, your spread is a little bit high and some calm parts are mapped completely contrary to your muzu:
Oni difficulty:
01:55:426 (7,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32,33,34,35,36,37,38,39,40,41,42,43,44,45,46,47,48,49,50) - 02:01:849
Muzukashii difficulty
01:55:426 (385,386,387,388,389,390,391,392,393,394) - 02:01:849.
Map along with your muzukashii and add notes if you don't know where to start. Wish you luck, and poke me when you have finished the Oni and gathered enough mods.
