changed a few of the things you suggested but overall i dont think its really possible to nerf the rhythm in this song much due to it being basically all 1/2, especially at 00:19:343 -> 00:34:995, i think what i have there is the most i can simplify it to while still following the rhythm in that section and not feeling awkward
reduced the spacing on 00:34:474 (3) - to match the other notes but i think any more change would make the pattern look alot worse + i already reduce the spacing across that whole section by making each individual pattern less spaced
