Chica de anime serena con atuendo futurista y patrones dorados

Generate a vertically composed ultra-high-resolution 16K anime-realistic image with a 9:21 aspect ratio. The character is Hatsune Miku seated in a diagonal pose, captured from a low-angle side-facing view. Her body leans gently forward, legs crossed and extended, left hand softly resting on her cheek, right hand relaxed by her side. Her expression is serene and gentle. She reveals her bare legs, shoulders, and collarbones. Her anatomy is well-proportioned, with natural limb positioning, accurate joints, and a symmetrical pose. Both hands have five clean fingers, with no distortions or extra limbs. Her legs are exposed, feet have five anatomically correct toes, and her face and eyes follow anatomical precision. Her outfit is a custom futuristic design: a mint-green and metallic gray cropped top with translucent shoulder panels and glowing chest detail, exposing the collarbones. A high-waisted luminous skirt features gold-trimmed Art Nouveau embroidery, fully covering the body while preserving visual elegance. Arms are wrapped in semi-transparent sleeves with metallic accents. Twin ponytails hang naturally, tied with Klimt-inspired golden ribbons. The background features Gustav Klimt-style spiral motifs, symbolic shapes, gold textures, and stylized jewelry patterns. Behind her is a softly lit decorative wall with intricate embossed florals and ambient lighting. The painting uses thick oil-style brushstrokes, saturated colors, and a complex layered composition. The result is calm, richly detailed, and masterfully styled.
