Thanks for confirming it, Gary. It was really more about the arrangement than about the mix. I roughly listed up all the changes in the Soundcloud description. I' ve done a lot of multitrack orchestral playbacks by ear without sheet music, but here I was deaf for a few important things first before I realized that in fact at most times two instruments are playing harmonies in parallel, and only one is improvising... As Dreamer said when we discussed this piece: How much you would learn from it if you elaborated all the instruments of that piece...
