00:38:368 (219,220,221) - 00:38:684 (222,223,224) - 00:39:000 (225,226,227) - 00:39:316 (228,229,230) - how do you feel about simply mapping it into 1/6 dddk instead of doublet 1/6 dd into k? it does fit pretty well with that melody that bounce back.
01:02:526 (460,461) - maybe change into a k & 01:02:684 (461) - into a D ? It does represent the increasing pitch a bit better and does actually flow pretty good with the whole pattern. thought, current pattern is good, so up to your preference
01:44:132 (770,771,772) - even if it fit pretty well, there's currently no introduction to 1/8 triplet during the whole map. Which make that pattern quite surprising and feel out of place.
I'd say, either remove that note 01:44:171 (771) - ; or make the pattern a 1/6 dddk
01:48:947 (817,818,819,820) - how about gradually, slightly decreasing the SV on those notes? It'd give more impact on the D here 01:49:421 (821) - ; and does in fact represent the fact almost all instrument stop here 01:48:947 - .
Something really light like this:
tho, using your value should work better. It's just a example.
