Make offset 667. Avoid having offsets in the minus section whenever possible.
00:00:982 (982|2) - Just make this a circle.
00:09:272 (9272|1) - Delete this note perhaps.
No hold notes at all from 00:24:509 - to 00:51:272 - then only two hold notes before 01:12:667 - I think you should utilize them more!
Overall though very good quality difficulty, good job!
00:08:719 (8719|2) - either delete this or map it at 00:09:351 - and throughout the song.
02:40:693 - Make a slider starting from here till 02:41:088 - to map vocals.
