00:19:468 (3,4) - there's a pretty noticeable drum sound between these two, and considering the map has been simplifying vocals and following the drums more so far, it felt a bit out of place to miss the 3/4 drum pattern in order to go for the vocals
I would take the chance to start following the vocals here (00:20:232 (1)). this is a memorable, distinct looking pattern, and you're switching from following drums to vocals on a change between vocal phrases rather than in the middle of the singer's vocals where you have it currently
00:37:621 (6) - I would cut this slider in half, you're focusing on the vocals here (I think at least) and so hitting the vocal at 00:37:812 would be nicer
i don't like syncopated rhythm like 01:03:799 (3,4) - in normal. maybe reverse 01:03:799 (3) - extend 01:05:328 (7) - to a full beat and delete 01:05:901 (8) -?
i didnt to reverse because it might be too much reverse slider "spam"
i think these 3 are enough 01:09:149 (1,2,3) -
