Elegant Autumn Fan Portrait

Create a delicate vertical anime-style watercolor portrait of {argument name="character name" default="F-shi"}, an elegant androgynous young person with pale skin, long platinum-blond hair swept to the side and tied loosely at the nape, and striking heterochromia eyes: one violet eye and one muted green eye. The character is shown from the chest up in a refined autumn mood, facing slightly left while gazing calmly and mysteriously at the viewer. A large white folding fan covers the lower half of the face up to the nose; the fan has pale ivory paper ribs, dark navy struts, and exactly two maple leaves attached near the center-right: one muted green leaf and one reddish-brown autumn leaf. One slender pale hand holds the fan at the lower left with long elegant fingers. Dress the character in a translucent pale lavender kimono or robe with subtle layered folds, white sheer outer fabric, and fine sketch-like linework suggesting flowing sleeves. Use a soft off-white blank background, airy negative space, faint pencil outlines, pastel washes, gentle blush shadows, and refined Japanese illustration aesthetics. The mood should be quiet, graceful, and seasonal, emphasizing {argument name="seasonal theme" default="autumn"}, with no visible text, no watermark, and no extra objects.
