Pretty, only a couple hiccups
I would say unless you expanded upon the empty space with the sounds of you fidgeting in front of the mic in the very beginning and make it an artistic part of this piece, i would try to cut it out of this.
I would say practice this a few more times cause there where a couple areas of hiccupage, but i only say this with love and with the hopes to help.
Maybe a couple parts where the you separate the high and low part with a melody that plays of it's own accord then a after a few beautiful measures of "solo" magic (I put quotes only because I don't mean like speed guitar solo, but more in the classical sense) bring the cording back in and either end it or repeat the beginning and then bring in another section then afterward the outro.
I hope this wasn't to confusing though. I liked it, you did a good job mixing it, and the quality is top notch. :3
