00:47:281 (4) - this sv decrease feels a bit unnessesary, its too much a decrease than the kiai before it so I think you should keep it around the same or decrease it by 0.1x.
01:20:784 (3) - you should map this at least until 01:27:792 (1) - since normal did it as well.
01:04:799 (1,2,3,4,5,6,1,2,3) - this needs to be nerfed, its too hard for the diff. I recommend making 01:05:456 (5) - a reverse slider ending at 1:05:675 to add a small break and even making 01:06:222 (2,3,1,2,3) - a quint burst to make it less rhythm intensive.
