add 00:20:204 (20204|0,20371|1,20538|0) - because this is too loud in the chorus to not be mapped
00:10:704 (10704|3) - should be set as a full 2/4 ln like this 00:10:704 (10704|3) - to emphasize the sound getting louder, similar to what i said in easy difficulty
i feel this difficulty should start at 00:00:705 as 00:00:705 (705|3) - just to make more sense on when the beatmap should start. add hitsounds however you want
i think you edited the beatmap which is why youre confused. you can take 00:10:816 (10816|2,10927|0,11038|3,11038|2,11149|1,11260|0) - from 00:10:816 - and ctrl + h to flip it to the other side, where you can then add 00:10:704 (10704|0) - to help define audio. hope this helped
at 00:20:204 you can add 00:20:204 (20204|1,20371|0,20538|1) - onto that part, singles because it's easy, you can do the same idea for hard w/ doubles if you'd like
