Hi jerry,
I liked this sample. It recalled me of the summertime.
I can't say which flute I like better - the yamaha sweet! flute or Pa1X Pro.

In addition to what Scott Yee said I'd like to mention that your flute solo sounded to me too 'keyboardish' - all notes were played legato. If I were you I'd play some of the notes non-legato with more expressive dynamics.

I hope this will help you to improve this nice track.

Regards,
George
