i suggest to map the drum sound including the hat also its ok to use 1/4 for this diff like 00:07:052 (7052|0,7130|1,7208|2,7286|3) -
00:24:552 - i think you can make some variation for this 1/4 drum. for example: https://osu.ppy.sh/ss/16645873/f483
00:25:489 - same reason. for 1/2 drum i think this will fit well on it https://osu.ppy.sh/ss/16645877/31e0
