at 0:56 you introduce a new sound, I don't like it, but at 1:24 you use it again and this time it sound good.
between 1:29 and 1:30 I heard a glitched sound, which is used again but at that particular time it sounds like an error
Thats all I can tell you I'm not an expert. Hopefully I helped you
Sounds good , is the voice original?
