how about using ar8?
ar7.8 is kinda counterintuitive to read the 1/1 overlap like 00:04:966 (1,1) -, especially in the intense sections.
compared with other sections, your kiai feels kinda underwhelming.
ex: 00:16:633 - i can see u use many doule / triple 1/2 rhythms to follow the vocal + drums in this section.
but it feels kinda weird when u use sparse rhythm to follow vocal in the kiai. (most 1/1 click)
so u can try to use more circles to cover the drums as well, like similar stuff on 00:53:966 - 00:58:133 - 00:59:466 - 01:02:466 -
