Wow. Thanks, every single one of you, for such wonderful and constructive comments.

Yes, the flute needed breaks. Schoolboy error. The original solo part is for violin, which obviously doesn't need breaks, so I just copied and pasted the violin part into the flute part without thinking that the flute will need breathing breaks. As I said, truly a schoolboy error! Will try to fix :-)

I'm so glad you enjoyed this piece. It's one of my favourite classical pieces, so I'm glad I didn't butcher it with my idea of how it could be arranged, haha. Thank you ever so much!!!
