From here 00:00:105 (1) - to here 00:09:650 - I think it would be better like in Muzu: following the structure K d d d K d d d because the first beat in this intro is alway more strong, so a kat is needed here. Also in this point 00:09:650 - there is an evident sound you did not mapped: I suggest you to add a big K.
00:09:991 (7,8,9,10,11,12,13,14,15) - This pattern is a little too difficult for a Oni, it might fit well in a inner, but here I suggest to semplify it a bit, like from this
to this
00:11:014 - Here the pitch is high, I recommend a big K
00:14:423 (13,18,34,37,40,45,69) - These notes should be k for the same reason I told you in Muzu
00:12:292 - consider adding a d here: a ddk pattern fits well
00:17:747 - same
Consider adding d also here 00:13:827 - and here 00:13:912 - so you increase the number of notes and the star difficulty of the map so it can be balanced with the others (and also because a kdd pattern sounds cool there)
00:19:281 - same? (suggestion)
00:14:934 (19,20) - Change to d? It is a suggestion, this is not necessary
00:20:219 (53) - if you change it to k the whole pattern would be mirrored and it sounds cool too! Don't you think? ^^
00:37:605 (143) - Like in Muzu I suggest to turn this into d so you keep the structure k d k d
00:40:332 (150) - same
00:41:696 (153) - same
00:42:378 (154) - same but from d to k
00:45:105 (2) - same but from d to k
00:47:150 (7) - same
00:47:832 (11) - same but from d to k
00:49:196 (16) - same but from d to k
00:53:287 (30) - same but from d to k
Maybe add a d here 00:53:372 - and here 00:54:054 - ?
00:54:650 - same problem with the kiai section, see what I wrote you about in Muzu
Another suggestion to buff a bit your Oni: in the section between this 00:32:832 - and this 00:54:650 - you should put more notes/patterns, your choice which and where, but this is a Oni, do not map it like a Muzu
00:54:650 (39,43,49,60,69,73,84,88,4,8,15,20,25) - These notes should be k: same as Muzu. Maybe these 00:54:650 (39,52,76,80,95,4,8,25) - with a finisher too (I might have missed some, I trust on your good ear to find the others
)
01:05:559 (84) - if you change this into k (like suggested above) I recommend to change a bit this pattern (which is good, but if you put a k at the end is more 'meh') 01:05:048 (78,79,80,81,82,83,84) - instead of ddkkkkd you can do something like ddkkddk or kkddkdk, your choice ^^
00:54:650 - Here begins the ending. I think there are too many breaks for a Oni in this section, you should fill up a bit. I can suggest you something based on my tastes,
of course you always do whatever you want, it is YOUR map, do not forget it ^^. For example you can:
• Add two d here 00:55:673 - before the k so you make a ddk pattern, which fits well and is appropriate to this diff
• Add a d here 00:57:037 - so you fill up that huge space a Oni do not need
• Add two d here 00:58:400 - like I said before
• Add a k here 00:59:849 - here 00:59:679 - and here 01:00:020 - so you build up a new pattern good for a Oni
• Add a d here 01:01:128 - fill up (I do not wanna write all the sentence again XD)
• Add a d here 01:02:491 - fill up
• Add two d here 01:02:662 - new pattern
• Add a d here 01:03:855 - fill up
• Add two d here 01:06:582 - new pattern
• Add a d here 01:07:946 - fill up
• Add a d here 01:09:309 - fill up
• Add a d here 01:12:122 - and a k here 01:12:292 - new pattern
• Add a d here 01:13:486 and here 01:14:338 - new patterns
• Add a d here 01:14:849 - and here 01:15:020 - and a k here 01:15:190 - new pattern
01:16:469 (47) - Please this note does not fit at all. I recommend you to finish like in Muzu, as I suggested in one of those two ways: it will sound a lot better ^^
