04:20:632 (3,4,5,6,7) - 04:20:632 (3) - https://imgur.com/a/X5HPJlR reduce the lenght of the slider and move all these notes foward 04:21:046 (4,5,6,7) - to 04:21:046. It should make way more sense to use the vocals. But you will need somthing here 04:21:873 so you could move 04:22:080 (1) to there and adjust the timing to x0.75 instead of x2. Or you could just add another slider all up to you.
01:35:935 (3,1,2) - 01:36:108 (1) - make this go inbetween 01:35:935 (3,2) so it becomes 01:35:935 (3,1,2)
01:30:763 (4) - ctrol H and move 01:31:108 (6) - to bottom left and this 01:31:625 (1) https://imgur.com/a/Y2oniMc. and move 01:31:970 (2) - to the right a bit
01:25:763 (1,2) - change both into normal sliders; so the build up till the stream will be multiple sliders.
05:25:184 (4) - give this slider more duration till here 05:25:494; or you can make another slider from 05:25:391 (5,1) - it should clear somethings for you too look at. The problem is at the transition with over mapping.
Some times little changes in notes means alot. Try to think this segment as somthing its own element try to convey the logic of the w h y in the way you did it. Here is an example, 03:26:425 (1,2,3,4,5,1,2,3,1,1,2,3,1,2,3,4,1) that you have done.
