00:31:084 (31084|0,31215|0,31345|0,31475|0,31606|0,31736|0) - I admit this pattern looks skill but it could use a switch not to fill this column for 6 notes straight like this:

00:47:258 - 00:51:432 There is one thing I do not understand about this JS section and it's the placement of the doubles, I can see highlight on the vocal-like sound, but I think it is undeniable that there is a stronger beat each 1/1 beat that is normally represented as singles in this section, although later and earlier were represented as doubles, is there a reason for this? because maybe the JS until 00:55:606 could be more consistent

In the Jumpstream/Handstream section you are not being faithfull to your rhythm choices. I notice if you slow down the music you mostly place a triple for the "claps" and then have a double for each beat on 1/2. That's your decission but you do not keep it throughout the section:
00:37:405 (37405|3) - should be double.
00:37:605 (37605|3,37605|0,37605|2) - should be double.
00:37:905 (37905|0) - should be double.
00:38:205 (38205|2,38205|3,38305|0,38305|1,38405|2,38405|3) - should be triples.
00:38:605 (38605|0) - should be double.
00:39:405 (39405|0) - should be double.
These changes would make the theme consistent.

00:35:205 - Pretty clear cymbal I think it ought to be a triple.

00:20:805 I recommend the following pattern as I think the thunder is not worthy of being a double due to the intensity / contrast concept I introduced in my previous mod.

There's one important detail you must consider, if you choose to represent a piano pitch with a row of notes according to its density, in 00:09:605 (9605|1,9605|2,9605|3,9605|0) - 's case you have decided it should be a quad, then for the rest of the section every time that pitch is played it should be represented with a quad too. Although if we talk about intensity, as we're in the intro section I rather this remains a triple just like 00:11:205 (11205|2,11205|1,11205|0) - By this logic in my opinion:

00:12:405 (12405|0,12405|3,12405|2,12605|1,12805|3,12805|0,12805|1,12805|2) - should be Double - single - triple.
00:13:005 (13005|2,13205|3,13205|0,13405|1,13405|0,13605|1,13605|0,13605|2) - all singles.
