01:45:215 (418,419,420,421,422) - I believe it is better to map guitar instead of quiet drums: https://osu.ppy.sh/ss/17903233/2e2c
01:45:744 (405,406,407,408) - this currently feels a bit awkward to play since the sounds that are mapped are so quiet, so maybe you could map it like https://osu.ppy.sh/ss/17934348/487d to make the rhythm more easy to understand from a player perspective
