I liked your mix. To get even better, I would increase the volume of the voice a little, it seems to disappear sometimes. I would also emphasize the guitar of the chorus, it does some really nice details that would be nice to hear. In other words, the only thing to "get it right" would be the balance of volumes. Other than that, your mix is beautiful.
