Dang dude this was absolutely lovely! The vibes are top notch and the time signature changes were a really nice touch.
While I enjoyed the melody in your voice, I really like the part writing you did in your guitar tracks especially with the voice leading in the distorted sections. My only real bit of criticism, which may just be my personal taste, is that I might consider experimenting with different tones for some of those distorted lead lines near the end. To me each part sounds a little treble-ly and I would probably try playing with a darker/more neck pickup-sounding tone even if for the sake of variety.
Listening to the instrumental track makes me think I could really do more with the space in my own mixes, there's always so many little details in your work that I could probably hear something new every time I hear it.
Thanks for sharing this, and keep up the good work :)
