I like how thick you can get your voice to sound on the F#4's (I think that's what they are?). I feel it is more of a matter of obtaining consistency across your performance and keeping good habits up (a muscle memory+endurance deal). You can get a nice and dramatic wide vibrato that I dig. Also, props on the vocal fry! I've never used my low vocal fry like that in a performance before... it sounds rather cool to do.
Around 1:36 - I fear I wasn't sure what you were trying to sing there. I don't know if that's acceptable in the style you're singing, but I would personally prefer a little clearer diction.
Perhaps pulling too hard on "chest" as some would call it around 1:52. Check for lip/jaw tension and make sure you're supporting adequately (and not too much!) perhaps.
I hear an example of what I would consider a little excess nasality words "my love" around 2:05... it sounded to me like perhaps your soft palate was dropping down by the end of the word "my"
Impressive siren/slide to that F#5 (right? ha) too!
Try singing the song and feeling your jaw to see if your lower jaw is correctly dropping loosely down and back. In my case, it turned out that a lot of my tongue tension came from lip and lower jaw tension. I think you might be holding over some of the constriction from your consonants which are supposed to be much more transient tensions.
Feel around your lips and mouth when you're singing loud parts where you're really feeling/emoting the music through your consonants check to make sure your lips and lower jaw loosen up as soon as your consonant ends. Maybe think about emphasizing the vowel sounds more than the consonants.
It looks funny to feel yourself all over your face while singing, but hey we make enough weird noises when we practice anyhow... might as well look hilariously cool too, right?!
Anyhow, I'm definitely no professional... just a dedicated student. If any more experienced folks/pros wanna chime in and make sure I'm not suggesting anything harmful, that'd be cool.
