Elegant anime girl seated with flowing twin tail hair

Hatsune Miku, vertical composition, 9:21 aspect ratio, anime-realistic style, ultra-high resolution, print-ready at 300DPI. Character in seated pose, captured from a low-angle diagonal upward perspective, body gently leaning forward, legs naturally crossed and extended, left hand softly touching her cheek, expression calm and graceful. She reveals her legs, arms, shoulders, and collarbones. Waist is tightly tailored with slight abdominal compression. Body proportions are balanced, limb positioning natural, joint angles accurate, posture symmetrical. Hands are realistically rendered with five distinct fingers per hand, clean shape with no distortions or extra limbs. Legs are well-defined, feet with five visible toes, anatomically correct. Face and eyes follow anatomical structure, body symmetry maintained. Outfit is a premium custom Hatsune design: mint-green glowing cropped vest made of flexible tech fabric, with transparent shoulder straps and luminous chest accents. Bottom: high-waisted light-reflective skirt with embossed Art Nouveau-style metal trim. Arms feature semi-transparent dark gray sleeves embroidered with musical motifs. Twin tails flow naturally, tied with gold-patterned ribbons. Background features Gustav Klimt-inspired decorative composition: spiral patterns, symbolic shapes, gold textures, and stylized Art Nouveau jewelry. Wall integrates complex floral motifs and soft ambient lighting. Brushwork is thick and painterly, colors richly layered, structure intricate. The entire image is highly detailed, serene and elegant in atmosphere, with strong artistic presence, resembling a museum-grade visual masterpiece.
