00:01:724 (1724|0) - This LN doesn't represent anything that justifies this length. Also, it's a simple cymbal sound, I would also reduce the emphasis to just a single note.
Similarly, 00:01:099 (1099|3)
sometimes i'm not sure what sound you want to follow .
like 00:02:974 - miss vocal ?
or 00:01:255 - missnote ? vs 00:02:036 (2036|1) -
00:03:755 - wrong snapped vocal ? if not , still not sure 00:03:911 (3911|0) - is for what sound .
some double i'm not sure , either .
like 00:00:786 - 00:01:724 - 00:06:255 - vs 00:04:849 - , no loud sounds to add double imo , also , seems not cuz the quantity of sounds .
personal think maybe you can only add double to snares and cymbals .
