00:20:983 (5) - Add a clap here
00:21:152 (6,7) - Maybe stack them i think it goes a bit better with the drum, also this way you can keep spaced note for 1/1 mapping like 00:21:657 (1,2) or 00:23:006 (1,2) during the first section
00:29:747 (1,2) - This spacing is a bit weird, if you look at the similar previous circles you have
00:21:657 (1,2) - 1x
00:23:006 (1,2) - 1x
00:24:354 (1,2) - 1x
00:25:702 (1,2) - Increasing 1.2x
00:27:051 (1,2) - 1.2x
00:28:399 (1,2) - Increasing 1.3x
So i think 00:28:399 (1,2) should also be 1.3x spacing
00:31:096 (1,2) - Same remark
00:33:792 - I think its important the player hit a circle here to stay consistent with the previous patterns
00:39:186 (1,2,3) - Make (2) closer from (3) and farther from (1)
00:41:882 (1,2) - Maybe space them a little, this is the last pattern of the introduction section
00:43:230 - Remove that kiai from the timing section :p
00:45:422 (6,7,8,1,2) - During the test playing i found this rythm a bit confusing, but okay it might be me since 5.2 is just a bit above my current STD level. But maybe you can go for this rythm mapping to get it less confusing if you want
As you can see, the idea is simply to use the second rythm twice, the thing later on in this section you are using this rythm several times at 00:51:320 (1,2) or 00:56:714 (1,2) so i think its better to prioritize it over the first one
00:49:214 (3) -Just a suggestion, i dont really feel its a good moment for a very short slider so maybe switch it for a coming back slider like this :
00:59:916 (2,3) - Same suggestion
01:18:792 (3,4) - Maybe make them a bit closer, otherwise it almost seems they have the same spacing as 01:19:129 (5,6,7) while its completly different rythm
01:24:354 (1) - Just an esthetic thing, i think you should make this curvy to emphasize the slider velocity change
01:25:534 (3,4) - Same thing as 01:18:792
01:28:736 (7) - I think you should make them 2 circles connected to 01:28:905 (8,9) as a stream before 01:29:073 (1) The idea is to mark the middle of the kiai
01:40:534 (1,2,3) +
01:41:039 (4,5,1) - I think you should stack them to differentiate from the 4-circle stream you had in different patterns before
01:44:579 (4) - Move it just a bit to the right i think to make it closer from (3) and (5), also for the same idea as 01:18:792
01:45:927 (1) - Same as 01:24:354
01:48:202 (2,3) - Im note sure you should stack them, the drum is not suggesting any stack and the player might loose the tempo with it, i would recommend to make it a jump
02:03:961 (9,10) - I would have seen a slider instead of simple circles here. During the kiai, before those long slider either you use several different patterns either more based on stream or slider or both, and i think you should use the slider approach a bit more
02:13:230 (6,7,1) - What about removing all whistle HS for those, and adding clap at every slider head ? We approach the end of the kiai so i think it could be interesting to emphasize the clap hit sounding a bit more
02:26:377 (4) - I you want to map the small voice in the background you should make it a slider until 02:26:629
03:06:657 (2,3) - I think you should make them a single coming back slider to match better with the violin
03:07:500 (4) - This one really feels like a ghost circle, i'd move it to 03:07:332
03:43:038 (3,4) - Same remark as 01:18:792
03:57:870 (3) - Just esthetic thing, i think you should align the slider with the next one
04:03:432 (1,2,3) +
04:03:938 (4,5,1) - Same remark as the previous kiai, maybe stack them
04:11:100 (2,3) - Well this time you didnt stack them but maybe make it a jump (even small)
04:26:859 (9,10) - Same remark as 02:03:961
Nice map, sorry i cant really evaluate the difficulty spread since this is above my level but it seems alright anyway. The kiais are really intense and the hitsounding is well done. Just maybe find a finish sound to add at every kiai beginning it could be great :3
