Yet more improvements Ractor! :clap:
The tiny little bits of flat 'out of tune' vocals still occur between 1:08 to 1:26 (your pitching on the second pass is better, but still a little flat in places). Similarly, you're a tiny bit flat again from 1:55 to 2:16 on those lower vocal phrases - I don't think you need to auto-tune the entire phrase though, and the lower harmony vocals should be OK.
By 1:37 you're spot on in tune again, as you are for all those high sustained "FREE" phrases later on. As you mention that you're already using AutoTune, it could simply be that this plug-in copes well with tweaking the tuning of such long sustained notes, but finds it more difficult during more complex pitched phrases where you're bending some notes.
Keep up the good work!
