I've already played it, my tip is that if you notice it repeats after the solo, there are few differences at the beginning, practice the fast part more.
sry a bit late, in case u still need advice: this goes for all flute pieces in general, but try to aim your air towards your left elbow. also in measure 3 try to use the left middle finger and ring finger fingering if you arent already, it gives you a clear sound!! :)
