00:18:745 (2,3,4,5,6,7) - You should change this part, sounds like you need to make some sliders with bursts, but not a single stream.
I think the stream can stay but maybe you should make a bigger difference in spacing between 00:18:745 (2,3,4,5,6,7) and 00:19:195 (1,2,3,4,5,6,7,8).
I think something like this 00:32:995 (1,2,3,4,5,6,7,8) could be better.
I made the spacing from 00:18:745 (2,3,4,5,6,7) the same as from 00:17:845 (4,5,6,7,8). i think otherwise it would be kinda weird and i dont want to overspace 00:19:195 (1,2,3,4,5,6,7,8) since it's still pretty early into the song
02:50:395 (1,2,3,4,1,2,3,4) - As a stream player I can certainly tell you this part is not nice to play, I think there are a lot of other creative ways to map this portion
