00:56:189 (4,5,6,7) - this exact part creates different spacing logics for a 1/4 3-note stack. Make it similar to 00:54:849 (2,3,4) - so people don't get that confused!
00:59:374 (8) - It's guideline recommendation to avoid using 5-note streams. Maybe you should delete 00:59:206 (6,7) - and extend 00:59:374 (8) - on those red and blue ticks.
01:06:245 (5) - I recommend to fill this red tick. To maintain the usual spacing logic, create a note of a red tick and stack 01:06:413 (6,7) - into each other.
