sounds cool, only gripe would be to line up the timing of some of the bells/guitar sounds if you want it to be on a actual key. if not, then nothing to worry about. the mix is cool from what I hear.

There are some mixing issues here. There flute and guitar sound like they are in different places which gives the track a disjointed feel. Overall it sounds 'tinny' to me, I would warm up that guitar with some EQing. The flute is the lead on a lot of the track and it's very piercing needs a different EQ and a different re-verb on it if not just a totally different voice. The bells sound fine to me, but I agree with 3ny6ma they're out of alignment at a few points. The composition of the piece is fine however, it's a nice relaxing gentle-beauty sound with a number of applications. It just needs to be re-mixed and mastered.

As for a demo reel you'll want it to be 1-2minutes long with as many samples & genres as you can squeeze into that time frame.
