The guitar sounds crispy and clear, point up there. :)
Like Seprix said, I'd wish the lyrics would be more clear, but I myself don't know how to master those yet. Search it up somewhere on the web, I should do the same. :)
The flute is incredible, I love it, ONE MORE!
The "aaaah" at 1:44, it's alittle sad that it's autotuned, but oh well. :)
Also, the voice getting put over at 2:29 is too loud in comparison to the rest of the mix, you should (as said before) find a way to master this so it fit with the rest or leave it out, in my opinion.
Everything said is me trying on constructive critism, I'm sorry if I pushed some bad buttons. :)
