[Beginner]00:09:323 (9323|3,9951|0) - Rather than use these two LNs, why don't you use the 3/4 rhythm like you've been using in the very beginning? Like this
https://osu.ppy.sh/ss/7169959 // making some simple 3/4 yuss
00:13:407 (13407|2) - I would consider moving this to 1 since column 1 is really empty for the first two measures // the empty lane was intended, well its only 2 measures at all, i made the next parts filled with more 1st column
00:15:920 - Since the snare or whatever sound it is like 00:15:291 (15291|1) - still plays here, I would add a note in 3, and move 00:16:234 (16234|2) - to 2 as a result. // added LN while keeping the snare empty instead, to make some transition more clearer to play
00:51:574 (51574|2,51731|1,51888|2) - I would consider using control H here since 00:51:417 (51417|3,51574|2) - makes the pattern feel to right hand heavy imo. // oo done
01:01:469 (61469|0,61783|1,62098|2) - Again for hand balance, I would just flip the pattern to go from 3-2-1 instead since column 3 doesn't really do anything, and it'd bring a little weight off the left hand that way // sightly done
01:26:757 - I think it'd be fine to add a note here for the crash and snare similar to 01:26:286 (86286|3) - // oke
01:26:914 (86914|0) - As for this, I might make it into a 1/1 LN to represent the 1/8 drum burst. Might look something like this
https://osu.ppy.sh/ss/7170001 // mm applied in different way
01:32:255 - Might use a jump here instead since this kind of ends off the section and acts as the transition into the kiai. Also, there's a crash.
01:54:558 - Would again recommend using a 1/1 LN here for the 1/8 burst and to help lead into the next measure since there's a fairly big pause between 01:54:087 (114087|3,114873|1) - so it might be difficult for some players to keep time. // added LN and applied to reduce the big pause
[Standard]00:11:836 - to 00:15:605 - It's not that big of a deal, but I'm wondering why Beginner is denser in this intro section than Standard is (standard on left, beginner on right)
https://osu.ppy.sh/ss/7170018 I think difficulty wise, it'd make more sense to flip the pattern and bring the 1/1 to Standard and use the long LNs for beginner since it's a difficulty focused on the synth.
00:35:553 (35553|1,35710|0) - Thought this was a bit difficult to hit due to the short note being in encaged by the LN in 2. Might work to just flip them around like so
https://osu.ppy.sh/ss/717003400:46:077 (46077|0) - I think it'd be cool to move this to 3 for symmetry so that it's a 1-2-3 pattern followed by a mirror of that at 00:46:391 - with 4-3-2
00:53:302 (53302|0) - The synth ends at 00:53:930 - , so I'd consider ending the LN there and just adding another 1/1 LN in 4 or something for the change in pitch. // im not sure but the spacing in the LN end (release) made to represent the 1/4 notes and the pitch works either way i think o3o
01:04:297 (64297|1,64454|2) - This is just my own visual preference, but I think it'd look nice to move to 3 and 2 respectively so the pattern kind of rolls to the left. // applied but rolling to the right instead hehe
01:42:621 (102621|3,102778|3,102778|2) - This kind of note arrangement is really difficult to coordinate properly, and I think it's because the player is used to using a single finger jacking motion (like in 4), and so having to jack two notes and suddenly add another on the same hand throws people off a bit. I might try this instead
https://osu.ppy.sh/ss/717005001:49:061 (109061|3,109218|2,109375|3,109532|2,109689|3,109846|3) - I keep missing on this note, and it's probably due to the fact that you changed patterns partway through the hand movements. What I mean is that it goes from simple 1/2 one handed trill to middle finger stack. The one handed trill already makes the player used to a back and forth kind of hand motion, and the stack just throws it off, so I'd recommend moving it to the other hand, or arranging the pattern like this
https://osu.ppy.sh/ss/7170064[Hyper]00:20:946 (20946|1,21103|1,21260|1,21417|1) - 4 note stack is uncomfortable to hit imo. Plus that one handed minitrill with 00:20:946 (20946|1,21024|0,21103|1) - makes me sad. I'd try this instead
https://osu.ppy.sh/ss/7170070 since I feel that the two handed trills are slightly easier to hit // >A< okay don't be sad i change them
00:39:166 (39166|1,39244|0,39323|1) - Similarly, this trips me up quite a bit. Maybe move 00:38:852 (38852|1,39166|1) - to 3 instead? // k :C
00:40:265 (40265|3) - I'd consider moving this to 3 instead since it'd be a more consistent stack as it'd be similar in structure to 00:39:951 (39951|0,40108|0) - but on the different hand.
00:41:208 (41208|1) - Also, the previous measure to this was a bit heavy on the left hand, so I think it's better to move this to 3 on the right hand instead
00:46:548 - Don't see why you don't add a note here in 2 or something since the piano pitch is the same. If you do choose to make a stack, I'd move 00:46:705 (46705|0,46862|0) - so that it's more balanced on both hands.
01:24:244 (84244|1,84244|2) - This jump comes as a bit of a surprise imo. throughout this entire stream, there haven't been any jumps and you suddenly introduce one in the middle of everything. I'd rather this just be a single note and you save the jumps for when they're 1/2 apart instead since it gives the player more time to think and process the notes as they're coming.
01:38:773 (98773|0,99009|0,99244|0,99480|0,99794|0,100030|0,100265|0,100501|0,100736|0) - I think this might be a little too much for column 1. Compared to the other columns, which you tend to give about 3/2 beats of rest between each note, column 1 is taking a lot of the notes. I'd try an arrangement like this instead
https://osu.ppy.sh/ss/717011301:45:134 (105134|3,105291|2,105448|3,105605|2,105920|3,105920|2,106077|3,106234|2,106391|3,106548|2,106705|3,107019|2,107176|3,107333|2,107333|3) - Again, kind of felt unbalanced when I was playing. Might try something like this
