I love the deep bass right out of the gate.
The composition is nice, and the slight pitch shift is nicely balanced and integrated well. I also like the development coming in with the other synth later, it's also a tasteful addition.
The mix is well balanced as well. The electric piano in the upper range also does a lot for this.
I think my ear wants to hear the electric piano have a little more melody as it develops. You probably ran out of time, but I feel like after the electric piano cuts out, that would be a perfect place for percussion, a nice pattern built on 1-2-3-4-5-6 that adds some energy but keeps it chill.
Great work overall!
