I suggest highlighting this barline using low SV separately, which would highlight the abrupt fading wub effect at 00:09:081 ~ 00:09:319. To do this, shift 00:09:399 this note 1ms back and also 1.8x SV value 1ms back (you can do this in the map file or you can change the map offset to 1 back without shifting the notes, follow the steps above and then shift the offset back), then add a 1x barline to 00:09:399. As a result you will get that the barline will fly at 1x and the note will fly on top of it with 1.8x. It will also look harmonic with 00:08:129 with this barline.
04:00:510 (38) - should be similar to 03:55:431 (1) - with the sv and the finisher for consistency
04:00:589 (240) até 04:02:415 (258) ~ eu acho que seria uma boa ideia vc repetir essa gimmick de finisher que vc fez em 03:55:431 (202) até 03:57:335 (210), porque as duas sessões tem vocais bem parecidos e deixar as duas com um ritmo mais parecido deixaria essa parte mais consistente
minha sugestão seria copiar as SV de 03:55:431 (202) até 03:57:335 (210) e mudar o pattern de 04:00:589 (240) até 04:02:415 (258) para -->
04:32:255 - this is an awkward place to cut off the kiai, it's in the middle of the chorus, if you were to shut it off here at least wait until 04:33:525 - , but i would turn it back on from 04:36:065 - to 04:37:969 - cause this is a very intense ending to the song. I would also consider keeping it on for this entire portion of the song as well
