00:18:658 (1,2,3) - I think a 1/2 slider would work with the vocals here much better... Using triplets here also kinda takes away from the uniqueness of the earlier triplets by overdoneness. There is also no triplet percussion or vocals like in the previous one so having these also as a triplet seems a little overdone. The last one before the short stream e.g. 00:19:468 (1,2,3) - I feel will be fine as the 'sampler' before the short stream.
Also applies to 00:18:982 (1,2,3) - , 00:23:847 (1,2,3) - , 00:24:171 (1,2,3) - , 00:44:604 (1,2,3) -
00:34:387 (1,2,3,4,5,6,7,8) - I feel that the sounds at 00:34:387 (1,2,3,4,5) - are all of (imo) equal importance/pitch so it doesn't make much sense to start the 'gradual decrease in spacing' idea there but instead at 00:35:036 (6) - where the drum percussion is descending somewhat. Just a rough idea of an alternative (https://puu.sh/ILLbw/b580208e9e.png) but if you agree with the point, I'm sure you can come up with something nicer :P
they're all decreasing imo, and also the emphasis that 00:35:523 (1,2) - has is really strong as the pattern is on its y axis which gives a movement and visual emphasis due to 00:34:387 (1,2,3,4,5,6,7,8) - being pretty much all horizontal
00:57:090 (1,2,3) - vs 01:07:468 (1,1) - it would be nice to have both as 1/6 since the sounds feel important
01:20:279 (3,4,5) - mby u cld space this out more, esp from 4->5 cuz rn u dont rlly move much but at 01:20:604 - the melody gets a lot higher so this felt a lil weird
