Not really sure but 2nd kiai seems denser than the 1st kiai A LOT.
I think some notes should be removed for example 01:04:765 01:15:315
Also I think the forced 3/1 break at 01:14:655 - is kinda strange, you could adjust the patterns after to put some more blanks:

At the moment, there is not much difference density wise between the kiais and the other sections (in fact the other sections are even longer sometimtes). I would suggest making the non-kiai sections slightly easier to create better contrast between the more and less intense parts of the song.
