Excellent, excellent, excellent. Great flute tonality, excellent piano performance, nice musicianship between both performers. The interpretation, ornamentation, and emotion behind the playing. I would absolutely like to hear more!
First of all I admire anyone who can play the flute like that, because I really tried hard in high school and Jr. High, and I never could play anywhere near your ability. So that's an incredible talent to have. And the piano playing is also very good.
I enjoyed this song a lot since I know how hard it is to do all those runs. It is original and fun to listen to, sort of like a dance. I think there is an application in publishing for flute or with orchestral arrangers and publishers for school or symphonies.
