It's kind of funny that we uploaded covers of the same song 1-2 days apart. I really like yours!
(I'm going to give feedback because of the "Critique Requested" tag, but if you didn't actually want any, ignore everything below this.)
I don't think I've come across any other covers that added harmonies, and it helps make the voice stand out more. They're also in the key of the song, so they're not painful to listen to. I probably wouldn't have used them for most/all parts of the song, but that's just me. It's fine the way it is.
The mix sounds good from here, but I'm on mobile. I would think my computer would have better speakers, so I'll try to access it later and give better feedback on it ^^b
Overall, it's a really good cover!
