I listened to it, nice work.
Whenever I hear something in this style (any instrument), I listen for two things--groove and melodic-ness.
Since it's minimal instrumentation, there is a lot of responsibility on the soloist to keep the listener tuned in and waiting for more.
For me, the best part of the tune was right after the voice-over. The drumbeat had some swing, which matched up rhythmically with your melodic lines for several very interesting and connected measures.
The front and back of the tune had the lazy drumbeat, and your phrasing was a series of fast passages that kind of stood alone and apart from each other more. Don't be afraid to take your time with some of the phrases and link them together melodically when the beat is real laid back.
When soloing over that kind of slow beat, you could really play with the rhythm to make it interesting that way as well, without having to necessarily play too many different notes in a measure or two here and there.
Other than that, I was impressed with your facility on the instrument.
Good on ya' for asking for feedback. I've heard that "all feedback is a gift", and it is the fastest way to get objective perspective.
All the best,
