Shy anime girl floating in elegant golden art nouveau scene

Hatsune Miku, top-down perspective, body floating as if seated on a transparent chair, legs distinctly crossed and bent to the left, right knee softly folded, left leg lifting and crossing over with sculptural elegance, legs smooth and well-defined, right arm gently extended downward, left hand raised near the face in a bashful gesture, head subtly tilted left, wearing a shy smile, shoulders, collarbones and waist exposed, posture stable yet airy and floating, outfit custom-designed: dark high-neck but shoulder-revealing fitted garment, integrated with gold foil spiral patterns, symbolic motifs and stylized Art Nouveau jewelry elements, skirt designed with high slits flowing along the crossed leg curves, background encircled by Klimt-inspired visuals with golden swirls, symbolic shapes and soft white flowers used as ambient accents without overpowering the subject, ambient lighting soft, composition rendered with thick oil brush textures, visual ratio set to 9:21 without showing digits, five fingers per hand and toes per foot clearly visible and anatomically accurate, clean shapes with no distortions, natural joint angles and proportions, symmetrical body balance, face and eyes anatomically correct, overall a highly detailed, intricately composed masterpiece
