There seems to be a little bit of Klangfarbenmelodie with your timbres, but not all of them blend super well. The passage at around :28 lacks cohesion because of a lack of octave equivalence.
Mode mixture between major and Mixolydian modes was nice, but underutilized.
Cymbals can be quieter.
The pseudo modulation to the relative minor was cool in the way it was underplayed/unannounced. I don't think it works super well to not announce the return, however.
