優雅金色裝飾背景前端坐的寧靜動漫少女

Generate a vertically composed ultra-high-resolution 16K anime-realistic image in 9:21 format. The character is Hatsune Miku in a seated pose captured from a low-angle diagonal perspective. Her body leans gently forward, left leg extended naturally, right leg crossed and lifted, left hand softly touching her cheek, right hand relaxed beside her. Her expression is calm and serene. She reveals her bare legs, shoulders, and collarbones. Her anatomy is well-proportioned, limbs naturally positioned, joints accurately angled, posture symmetrically balanced. Her hands display five clean fingers each, without distortion or extra limbs. Legs are exposed and anatomically correct, feet show five realistic toes, her face and eyes follow precise anatomical structure. She wears a custom outfit designed for seated elegance, inspired by Hatsune Miku: a mint-green cropped high-tech top with transparent shoulder straps and metallic glow-accent borders. The chest is fully covered, while shoulders and collarbones remain visible. The bottom consists of a high-waisted skirt featuring embossed gold trim and musical symbol metallic accents, fully covering the hips and pelvic region. Arms are adorned with semi-transparent dark sleeves embroidered with spiral motifs. Her twin ponytails fall naturally, tied with Klimt-inspired gold ribbon. The background is filled with Gustav Klimt-style spirals, symbolic shapes, golden foil textures, and stylized Art Nouveau jewelry motifs, composing a richly layered decorative wall. Ambient lighting is soft and enveloping. The image is painted with thick oil-style brush strokes, deeply saturated colors, and extremely high detail. The composition exudes elegance and tranquility, rendered with masterful artistic precision.
