I think it would be a nice aesthetic tough to put 00:04:778 (4778|3,5207|0) - in 3 and 2 to contrast with the previous rice notes being in 2 and 3 and the LNs being in 1 or 4
00:28:778 (28778|2,28993|3,29207|1) - might be a good idea to pattern this sliiightly differently since it's the same as 00:26:635 (26635|2,26850|1,27064|3) - right now despite the vocal parts being very different from each other
(also applies to 00:30:493 (30493|1,30707|3,30921|0) - vs 00:31:564 (31564|1,31778|3,31993|0) - )
Ok so! About LN patterning in the kiais:
I think some parts should change a bit due to differences in the vocal parts. Specifically:
00:58:778 (58778|3,59207|0) - & 02:27:921 (147921|0,148350|3) - (when compared to 00:51:921 (51921|0,52350|3) - & 02:21:064 (141064|3,141493|0) - )
01:03:921 (63921|3,64350|3) - & 02:33:064 (153064|0,153493|0) - (when compared to 00:57:064 (57064|0,57493|0) - and 02:26:207 (146207|3,146635|3) - )
They are mirrored, but placing these LNs in the inner columns will have a much bigger visual impact when playing, and help to bring out the fact that these vocal parts are pretty different from each other
in regards to 01:05:635 (65635|0,66064|3) - , 01:12:493 (72493|3,72921|0) - 02:34:778 (154778|3,155207|0) - , and 02:41:635 (161635|0,162064|3) - :
If you agree the same principle could be applied here but eh it's not a huge deal, they're much more similar to 00:51:921 (51921|0,52350|3) - and 02:21:064 (141064|3,141493|0) - than the timestamps mentioned above.
I will mention that 02:34:778 (154778|3,155207|0) - and 02:41:635 (161635|0,162064|3) - are the exact same in the music though!
btw if you disagree with this that's totally fine, this is hella subjective lmao
