06:43:162 - way too sudden of a density change, need to reduce the ln ends and get rid of some of the doubles. the sound is pretty much the same as the very low density part right before yet the patterns do not reflect this. i would suggest keep the patterning the same as 06:35:482, and maybe you could gradually build up the density in relation to the sound if you really wanted to.
04:59:242 (299242|2) - this is just personal preference but could move this note to col1 as the sound doesnt repeat itself like the other two times it happens, and would accentuate the change in the sound better
04:13:162 - should add a note here as there is no difference in the sound than 04:13:282 (253282|1)
03:21:682 (201682|3,201922|3,202162|3,202402|3) - in my opinion, these lns should be moved down to here, as this would accentuate the more prevalent kicks, and as where they are correlate to no sounds. 03:22:522 you would also need to add a note on col4 here for the crash if you do this.
this is to represent the build up and slight raise of volume of the kicks to help build up the drop, from normal notes 00:41:737 (41737|3,41737|0), to 1/8, to 1/4
