Some 1/2 rhythm selection kiai feels off.
Just following drum makes really monotonous rhythm, so I suggest to try following dominant layers.
the rhythm choices sound really vague and switching casually between vocals and drums in the chorus.
for example, 00:38:980 (1,2,3,4,5,6,7) - while 123 are for the drums, 4567 are for vocals. i cant really tell the difference between 45 and 67, and why the latter 67 should be 1/2 sliders. meanwhile 6's tail stands on a kick, which makes 4567 neither fit the drums nor the vocals.
id say if you really want to fit the vocals, simply putting two 1/1 sliders works well and intuitive https://osu.ppy.sh/ss/17715080/1615. on the other hand since the chorus consists of long, extented vocals, it's fine to just focus on the drums for most of the time. in this case, i would suggest somewhat like https://osu.ppy.sh/ss/17715084/f3da
