00:53:484 (4,5,6) - prefer make it like this twitchy slider he fits the rhythm Of course these are my personal thoughts.

00:44:120 (1,2,3) - You can consider making something like this here. let the monotonous circle in this area become a little richer.

01:12:666 (5) - I like this slider maybe you can speed up the slider or something.
00:23:031 (1,1) - The circles are too far apart. You can consider overlapping them or placing them closer together.
Overall he's great !
03:24:868 (1) - Maybe you could consider placing this difficult kiai somewhere else since there is obviously no circle here
