This is an excellent example of what a thorough grasp of music theory can do for a composer (especially when they're capable of writing something worth listening to).
You use a wide variety of harmonic colors, a meticulous, nuanced arrangement, and a very intelligently written rhythm section (I can't emphasize this enough) to create one of the stronger arrangements I've seen on display in this community.
Even as your production skills continue to catch up with the rest of your chops, know that I still liked this when it sounded like crap.
Less saws next time, plz.
