Girl transforms playing flute from music room to bamboo forest AI Image Prompt

The background is a music room with many instruments stacked behind and some classmates practicing different instruments. In the foreground, a girl with a delicate and spiritual appearance wears a slightly messy low side ponytail, school uniform, and black-rimmed glasses, looking like a standard student, but with a green-to-blue gradient ancient-style mark on her forehead. She holds a jade blue-green gradient transverse flute (heng di) with a tassel at the end. As she prepares to play, a light blue butterfly lands on the flute. She whispers in slight surprise, 'Is it you?' Then she plays the flute, and as the sound rises, she almost closes her eyes but not completely. The butterfly flies up and covers the screen. When the butterfly moves away, the girl has changed into an ethereal, well-designed green gradient ancient-style dress, with ancient-style hair and makeup (no glasses), and the background is now a bamboo forest. She seamlessly continues the closing-eye and flute-playing motions from before the transformation; the mark on her forehead remains. Wind blows, a few bamboo leaves fall, and her hair, dress hem, and the flute tassel flutter in the wind. The entire transformation should be accompanied by ancient-style music that evokes a sense of surprise and contrast.
