Your writing is pretty great. I especially enjoy your surprising chord progressions.
I think the mix is okay for what it is. The drums make mixing everything else a bit of a challenge. I think the organ chords on the sides are pushing the rest out of balance. I would take them down, bring the bass up, and bring the lead up.
At times it was hard to understand exactly where transitions were going, and reverb made the melodies a little unintelligible, but I think you did a great job with what you have.
Thanks for coming out to NGUAC!
