01:46:117 - thinking u could remove this note cuz the kiai before it is the biggest group of note in this map, removing this note not only gives it a longer break but it also build a better tension towards the next section along with the music
01:48:777 & 01:51:141 - feel like these 2 gap should be filled instead of 01:52:324, the whole group of melodies are connected and breaking them with forced rest moments seems a bit odd, especially combined with the suggestion above I believe the break at 01:46:117 would be more than enough
