Effective, quite nice. Not sure how I feel about the sudden pedal stops, where all the resonating strings cut out, it's kind of jarring. When I listen to minimalism, I tend to go a little trance-y and the sudden stops my reverie is broken. That's a useful tool, but maybe not so frequently as to fully interrupt my journey, so to speak. Odd ending ... from a composition standpoint it makes sense, but it's a little abrupt sounding - might benefit from being extended or from a diminuendo, something to let us down softly.
Also I love the sound you've captured in the recording, super clean and mellow. Lovely!
