Synth was unexpected in a good way [edit:, but I must admit that on my second and third listen, I started liking it a little less. As a disclaimer, I am not a 'synth guy', so don't put too much stock in this].
Really excellent and interesting arrangement. Really well thought out and crafted. I was pretty fixated on what was coming next.
Looking for more growl and power from the bass.
Like the sound of the acoustic a lot.
Drums didn't always flatter the rhythm of the song. Sounded a little stiff here and there.
Vocals seem a little bit too out front of the rest of the mix (along the z-plane).
Lacks dynamics a bit which is a shame because this song really wants to breathe. It currently feels a little 'squished/limity'.
Very good overall though. I enjoyed the listen despite the little nitpicky stuff pointed out above.
