add note here and focus on the repattern of this 1/4 fragment of the map because the arrangement of patterns seems terribly random and poorly balanced. Many anchors could be reduced or even eliminated in some situations (use zoom out to look at patterns).
the same applies to this part 02: 05.381 when it comes to reppatern
I'm not sure if these LNs are needed for such barely audible sound even at a 25% slowdown but if you really want to leave them 120281|3 move this to column 1 or 4. I don't hear anything that indicates it's the same tone of sound. You should also add LNs here 02:01:181, 02:01:481 and here 02:02:381, 02:02:681
Leaving this up to yahweh's discretion
this part is weird due to the fact that at the beginning the sound is clearer on 1/1 and later on 1/2. To avoid this, add notes on 1/1 … It will be more comfortable and a little more varied
trill fits more here so wdyt about moving to 
move this note here 01:40.631 because here is the same sound as here 100331|2,100331|1,100406|4,100406|3,100481|2,100481|2,100481|1 and obviously this is unecessary ghost note 100706|3
100706|3 is mapped to the main melody (can be easily heard at 25% playback) while 100331|2,100331|1,100406|4,100406|3,100481|2,100481|1 is mapped to the 1/4 beats
the same situation as here https://quavergame.com/mapsets/map/3615/mods#69 so remove this note. Remove also 88931|1, 90131|2, 92531|4, 93731|4 etc
add note in column 2
I'm not sure but if you want you can move this note to column 3
move one column to the left for better balance and comfort
what do you think about moving this note to column 3? it seems to me that jack with double notes here fits more. You can also add note to column 3 instead of moving. Then you'll have a triple note here which will also fit because is the same as this 19181|1,19181|3,19181|4
this note isn't needed here. I know why this note is here but you are currently using a note and LN for slightly stronger sounds in 1/1 so doing the same for 1/2 with a softer sound is inconsistient. Remove also 12131|3, 13331|3, 15731|3 etc.
