In the intro, I feel an imbalance between the acoustic and the flute. i think both are panned to opposing sides leaving nothing in the middle. I couldn't figure out which to listen to with priority. It works when vox comes in. Maybe during the intro and flute solo break, you can pan the flute to the center and then find something else to fill in on the left side. just an opinion, though...
I agree with the others about the drum intro. Maybe just start the song with all instruments.
The song ends abruptly.
Nice arrangement. You have a nicely unique style, at least one less traveled, and you stay true to it. Very cool.
Cheers,
