00:02:118 You should make this a double to match with vocal's intensity
00:04:414 Instead of making another sandwiched trill, you could also use jumptrills to differentiate the higher-pitched singers's voice from the lower-pitched singer; e.g:
00:43:062 could be subjective, but the release of LNs at strange snaps such as this is not recommended at easy-normal diffs -> move the LN releases to 00:43:139
same for 00:53:470
01:01:353 (61353|3) - ghost note (highly recommended to remove)
01:40:690 - My suggestion would be to reduce vocal presentation and focus on instruments, but fully depends on your preferences
How I'd change 01:40:690 - 01:44:363
And ghost note - 01:44:975 (104975|1)
