Hey Tom,
here is some feedback:
I am not a fan of the vocal processing it sounds kind of robotic and abrasive to me? Is this a very tiny room verb or delay of same sort?
Anyway, If you want to use this effect to achieve a certain atmosphere or creative effect you could leave it as is, otherwise you should revisit that in my opinion.
I really enjoyed the small but very effective acoustic guitar edit at 0:50. Very cool!
The treatment of the piano also is great.
The drums samples work for the most part except the snare. I think its a bit hollow sounding and does not blend in.
To me it sounds like you are going for a distorted, squashed sounding chours.
I wonder what the drums would sound like if you squashed them even more and really killed the transient to achieve that Loudness War sound...
Usually I am no fan of this but I suspect it could work here
I think you achieved a distincitve and creative mix of this tune. My only real gripe is the vocal processing on the main vocal. Otherwise a nicely crafted mix.
Cheers,
Lukas
