This work has two parts. The first is conscious of color, and the second half is about feeling and flow.
The flute family is often thought of one that does not change its timbre so much, but if you devise a way to mix the overtones, you can enjoy various timbral changes.
Also, because it has great motility, it is also good at quick movements. In the first half of the song, I think it's best to keep in mind that different tones are used in different parts. In the second half, try to maximize the sense of dynamism.
