This is one of my favourite compositions of yours. Your songwriting/composing is always really incredible. I don't know many that can write as well as you do. As always, the lyrics are amazing.
In terms of the vocal performance, I think some parts are really great, and some other parts seem unstable. I know that you're going for the fragile dynamic that doesn't always call for a straight tone, but I think it takes a lot of control and attention to detail to really get the right balance between performing emotionally but also as pleasantly as possible.
For example, in the quiet verses, it does suit the part, but at the part at 1:38, because it's a rise in the composition and a swell of strength, the voice wavering between flat and sharp in my opinion isn't as effective as if you'd balance the delicate performance from the previous verses. When you sing 'you', in the 'can you hear me screaming', it literally shifts off the note of the melody four times in that short half a second and thus isn't as emotively powerful for me as a listener as it doesn't come across as intentional as it had in the quieter parts.
The part at 5:23 onwards vocally is really nice though! Those harmonies are really tightly performed and your breath support is really nice too. You sure can hold those notes well!
I really enjoy the choice of instrumentation and I love what you've done with the Celtic harp!
In terms of the mix, it's fairly clean and some of the instruments are mixed in nicely. Generally, I think the track could do with a bit of brightening in the mix. It all seems to be on the lower end of the frequency, which may be because you wanted a darker atmosphere, but it sort of makes the overall tone of the piece mixing-wise sound a bit dull. Almost like the difference between a pre-master and a mastered version of a track; when you switch back and forth between a pre-master and a mastered version of a track, so much is brought out in the master and it sounds like night and day. Did you master this track out of curiosity? :)
I hope you don't feel put down in any way by this review - a big part of what I enjoy about the NG review system is being able to impart constructive feedback! I wouldn't be where I am now without the honest opinions of those around me, and I'm ever-grateful for it. Your songwriting and composing is so top-notch, that I want to encourage the other aspects of the musicality to match that level! :) keep listening, and practising!
As always, it's a pleasure to listen to and an instant fav from me :)
