snaressnare sounds like 00:03:806, 00:04:455, 00:05:104, 00:06:401 and so on are worth to emphasize in my opinion
SPOILER00:34:617 - 00:38:185
00:39:806 - 00:43:374
00:44:996 - 00:47:915
these 3 sections and the later parts would be better if there are patterns to follow instead of loose notes
the current pattern looks kind of random
