I like the track a lot.
As for the sax, the tone is a nice inclusion, but the notes are a bit static. It feels a bit like a bass harmony riff that was brought to the fore as a treble solo. Woodwinds offer so much articulation in their dynamic range, it feels a bit like a missed opportunity to have one strongly featured while playing a more traditionally brass-style sequence. Always good to experiment though.
Again, great piece overall.
