00:21:494 - just minor thing, it's a shame that the drum part (HOpen) is not given an object even though it is loud enough to hear, so I can suggest adding an object col.2 and remove 00:21:673 (21673|3) - to reduce the density.
00:32:214 (32214|1) - I think it's better to just delete this to reduce the excessive density.
If you look at the melody, it's the same as before 00:28:820 (28820|0,28999|2,29177|3,29534|1) - .
00:29:356 - In this section you don't add objects
00:35:072 (35072|3) - same case
00:40:788 (40788|0) -
00:43:646 (43646|1) -
00:56:685 (56685|0,56864|1,57043|2,57221|3,57400|1,57757|2) - after using 4 densities then adding 3 sliders on top, I think this is quite difficult for easy diff, So my suggestion is to reduce the use of the slider above to make it simple
01:14:933 (74933|1) - Just a minor thing, I think this more comfortable if at col 4, so it's not create a OH trill 01:14:933 (74933|1,75111|0,75290|1) -
