00:54:080 (54080|2) - https://osu.ppy.sh/ss/17946510/6bee It seems to me that you accidentally overlooked this sound, as you highlighted it here 00:56:773 - and 00:58:183 -
01:19:977 (79977|2) - Subjective thing. Personal won't use LN pattern which involved into two cols here.
Because there's no other 2 col pattern in this diff, includes doubles.
So holding two notes here might be a bit stand out. Would be more natural if there's an optional pattern imo. (Ofc if you feel here's the most intense part and a want to emphasize, you can keep this.)
02:12:284 (132284|2,132669|2,133053|2,133310|3,133566|2) - Minor point here, but i think you can try to rearrange to avoid the stack here
Based on your pattern, i believe it should be devided into '2 parts' around 02:13:053 - , which will discourage the stack here imo, also you can refer to 02:16:900 -
