In A Chinese Temple Garden [A. Ketèlbey] - Flute Quartet

I'm still busy mastering the flute, here is my attempt at "In A Chinese Temple Garden", yet again by Albert Ketèlbey.
At the moment, I'm mostly struggling with fast runs in the upper registers and breath control for long legato melodies. Precisely what is required in this piece :)
