00:05:000 (12,15) - add dd to make this kddk, since you map the same sound at 00:07:787 and 00:25:579
00:17:004 (44,45,46) - if you want to contrast this double i would make it dd d
The ending has a lot of repetitive patterns as kddk, i would make them all unique esp since they dont all sound the same,
here's what i would do but change as you like
00:20:434 (50,51,52,53) - dddk
00:21:720 (54,55,56,57) - kkdk
00:23:007 (58,59,60,61) - kkdd
00:25:579 (66,67,68,69) - ddkd
