actually i do agree about 1/8 not fitting at all there '^' even though there are looooong sounds which she was trying to follow, it does feel that they are not really fitting.
as for my opinion i'd highly recommend:
・00:38:926 (1,1,1,1,1,1) - 00:38:926 (1,1,1,1) - to make this part be 1/1 still, as there are clearly hearable 1/1 beats; 00:41:701 (1,1) - make a streams from there - 00:41:874
・01:04:938 (3,4,5) - to remove that triplet cause its totally out of music
・01:26:094 (1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,1) - to make those be constant 1/1. the stream does feel weird and out completely out of beats, its invented
・02:10:487 (1,1,1,1) - 02:10:487 (1,1) - to change this to stream; 02:11:874 (1,1) - to delete this, lol. there is a compleeeete silence in beats so um, a little break and then baaaaaaaam kiai would be a nice part imo
・02:53:493 (1,1,1,1) - to stick to 1/1 rhythm there
