Dude you're blasting at this in chest. My honest advice, if you want to sing this style, I'd do some extensive pitching exercises. Forget about high notes, forget about a lot of stuff. Just super hard work on intervals, drone notes, ear training, scales, and singing really slow, every note on the piano or whatever instrument you have access to, on all vowels (including things that use R like world, her, mars, etc).
 
You see I like a lot of singers whose aren't pitch aren't perfect, I'm biggest Lou Reed fan of the forum, and if you do a more talk singing style then some of the pitching issues are more forgivable. But Dickenson/Tate these guys with their operatic metal kind of thing, it's very sustained notes, and it doesn't just glance or bend around them, it hovers and it stays. 
 
Maybe rehearse the song with the piano or something. If you don't have a real instrument you can use something this:

As slow as it possibly needs to be. Pick out the entire melody of the song and match it one by one.  I think you can get it, but to my ears, the notes are just too sustained for it to hold together for me. If you glance on a flat note, and pull up or glance on a sharp note and pull down. It's different than if you hover on one and just hold it. That's my 2 cents. I saw you've been working your sirens. And that's good, it will train a lot of things. But I think you'll get better progress on the other direction. The slower the better if you want to sing in this style. The bar has been placed high on this style. I'm not an expert, but it's tough. You're gonna have to keep training hard. It's one thing to be able to make a high pitch sounded physiologically. It's another to sing a whole song with the control that might be expected in this genre.
 
One things for sure, you put a lot into. Sounds like you're blasting and really in the moment and passionately performing and I don't want t be harsh, but these are your heroes, so put all you got into it. I think for most people, it will have to be closer, unless you're working on a different style.

Nice high notes, well done. You need more confidence though (not saying you arent confident) but your voice needs more 'punch', to be bolder.

Nice. You have a delicate voice (compared to eddies) but rockin at the same time. Nice combo
