Mix / Production
Well balanced mix
Thanks!
Instrumentation
The track suddenly sounds slightly empty in solo section at 1:58 – you may have taken too much out
Nice lead guitar sound - had me thinking of Gary Moore
By design. After building the track up until the chorus I wanted to drop things down again for the return to the guitar theme leading into the third verse. I listened again after reading your comment and still think it works, so we will need to agree to disagree on that

Vocals
Not that keen on the unison lead, but maybe that’s just me. I prefer the alternate line verse.
I like the harmony sections though
Fair enough.
What I really liked
Intro certainly grabs the attention – I like the repeat of the intro riff at the end. Nice touch.
Thanks!
What could be improved
Solo at 2:44 sounds too long to me
I’m hearing a lot of ‘lonely’ in the lyric!
Well, the solo is the length of a verse, which to my mind isn't too self indulgent. Unless you don't like guitar solos of course

And yes, it's a song about being 'lonely'.
Thanks for the listen and honest review, I appreciate it and respect your opinion.
