00:06:766 (6766|2,6766|3) - highly recommend to start this 1/2 later

00:15:766 - 00:23:766 - 00:41:766 - 01:03:141 - 01:36:766 - 01:44:766 - 01:52:766 - these place you can design some 120 minijack and I don't think this will beyond the difficulty limit

00:15:766 (15766|3,15891|3,16016|1,16141|1,16266|2,16391|2,16516|0,16641|0) - this pattern makes the gap with EASY very afar -- I recommend to alternate between rolls and jacks something like this

here too 00:23:766 (23766|0,23891|0,24016|2,24141|2,24266|1,24391|1,24516|3,24641|3) -
here also 00:41:766 (41766|1,41891|1,42016|3,42141|3,42266|0,42391|0,42516|2,42641|2) -

00:26:766 (26766|2,26766|3,27016|2) - try avoid stuff like this as it may be a bit dense for this skill level

00:30:766 (30766|3,30891|2,31016|1,31141|0,31266|3,31391|2,31516|1,31641|0) - can't hear anything here related to any sound in the song, I think it is played in the right-channel right? (LR) if it is then it's fine

00:33:016 (33016|0,33391|0,33766|0,34141|0) - long jacks of LN are not a good idea for this skill level, just make it alternate between 2 collumns

00:42:766 to 00:49:766 - I'd consider reducing the amount of doubles here, just to make a balance between EASY and BASIC's structure
would be good to change into single notes here 00:43:141 - 00:43:891 - 00:44:641 - 00:46:641 - 00:47:391 - 00:48:141 -

for the same reasons 00:45:766 (45766|0,45891|1,46016|2,46141|1) should be nerfed down to 1/1 notes only
00:48:766 (48766|1,48891|3,49016|1,49141|2) - tricky trills, I'd recommend to nerf this down a bit

00:42:891 (42891|3,43016|2,43141|1,43141|3) - this type of pattern may be akward for someone at this skill level. god damn why am i suddenly sayinf skill level so much

00:52:766 (52766|2) - this is a bit random since in the lowest diff, you mapped the other sounds rather than just the louder synth. i recommend charting the sounds behind it instead

01:00:266 - doesn't violate any RC guideline but this seems kind of sudden, despite it's accurate representation in consecutive kicks
maybe starting the 1/2 streams here 01:01:766 can calm it down

01:13:766 to 01:19:766 section is different than 01:05:766 to 01:13:766 section
so to differentiate them I think in the first section only applying doubles to snares can make a balance into the difficulty itself

01:17:432 (77432|1,77599|0) - these two should be in the 1/4 snap instead

01:17:599 (77599|0) - this is placed early and should be in the red line

01:19:516 - put a note at the 4th lane for the transition?

01:29:016 - missing representation of the snare?

01:37:516 (97516|2) - could move to col 4 to differentiate the drum sounds from 01:36:766 (96766|0,96891|0,97016|3,97141|3,97266|1,97391|1) -

01:44:766 (104766|0,104891|0,105016|3,105141|3) - other sounds are way more prominent than the consecutive kick for jack structure, I'd suggest to follow up rolls

01:45:266 (105266|1,105391|1,105516|2,105641|2) - same here, 1/4 kicks are way louder, 1/2 rolls should also be fine

01:45:766 - this kiai section is kind of a spike here, lots of consecutive 1/2 notes that don't follow an appropiate gap with EASY -- I can't think of a good pattern rearrangement for now so, I'd suggest to nerf this

01:48:266 - For consistency I think this place need to follow the vocal still, 1/3

02:00:766 (120766|3,122766|2) - unsnapped?
