Right off the bat, I'm not sure on those low down chords. I would either take the piece up a couple semitones if you want to keep those inversions, or space the notes out some more. Chords stop functioning the same way, the lower they are in interval, due to overtones conflicting.

I'm not the biggest fan of your lead writing throughout -- we pass over a lot of the same notes up and down, don't emphasize the peak of the melody a lot, and resolve down almost every time, which is fine! But it leads to sounding like you've written a countermelody, not a melody. So maybe a little studying of lead writing.

Mix wise, your percussion is hiding somewhat under all the other instruments. I would turn them down until the snare and kick cut through nicely.

Also, I caution from using reverb to give a piece width, warmth, and space. Always turn it lower than you think it should be, and cut low end on it up to 250 hz so you don't get that boxy low wash cluttering your mix.

Otherwise, good piece. Enjoyed the listen.

Thanks for coming out to NGUAC!
