Very nice! 
But shouldn’t “you” and “do” be pronounced /y uw/ and /d uw/? The sound like they are using /ao/ instead of /uw/.
But an very nice rendition!

I changed the phonemes because the “uw” sounded weird in that part. I tried changing it to “uh” at first, but it still wasn’t quite good to my ears.

To be honest, this is the first demo that made me think I could perhaps use NineZero. But I’m a bit concerned about key phonemes being absent.
The Australian /uw/ isn’t really different than the US version.

I went back and fixed the phonemes. I think I made it work. Let me know what you think.

Is it my imagination or is there some sort of artefact, most obvious on longer ‘aaah’ sounds such as at 1:40.
It may be just that this song is pushing the voice out of its comfort zone?
A penny for your thoughts on this 
This voice would do Ozzy No More Tears really well I think. I keep hearing Ozzys sound in all the covers so far

NZ sings in a Black Sabbath cover band called Blood Sabbath, so he’s definitely influenced by Ozzy.
