Female 3D poster dreamy retro aesthetic

An adult Eastern fantasy female character, dreamy and beautiful 3D CG high-precision rendering style, 9:16 vertical composition, sitting in front of a black grand piano quietly playing. The atmosphere of the image is like a high-end fantasy movie poster, soft, romantic, ethereal, and exquisite. The character is located on the middle-right of the image, elegantly seated sideways, waist naturally cinched, shoulder and neck lines soft and extended. The sitting posture presents an obvious but natural S-shaped curve. The character has a plump and graceful figure, mature and healthy, with naturally full bust-waist-hip proportions, overall displaying a high-end and restrained feminine beauty, the upper contour of the chest is visible, and the temperament is mainly elegant, soft, and dreamy. She has delicate and soft Eastern fantasy facial features, fair and translucent skin, fine texture, with soft subsurface scattering light. Her expression is quiet, gentle, and focused, slightly lowering her head to gaze at the piano keys, her eyes calm and dreamy. She has ultra-long smooth hair, naturally falling over her shoulders, back, and chest, with light and delicate strands, and soft matte highlights. She wears a blue dreamy flower hair ornament by her ear, paired with small gold earrings. Her outfit is a light blue-purple fantasy gown, made of thin layered gauze, with a soft translucent feel and starlight particles, flowing gauze sleeves on the shoulders and arms, and the skirt naturally spreading out. The outfit fits her body but remains high-end and restrained, highlighting soft feminine curves and a plump figure, without being overly revealing. The fabric has delicate pearlescence, light blue cold light, and a slight stardust texture. The scene is a dim, high-end classical music room. On the left is a black high-gloss lacquer grand piano, its lid open, the surface reflecting window light and purple petals. The piano keys are clearly visible, and her hands are naturally placed on the keys, fingers slender and elegant, playing. In the background are tall vintage windows, letting in soft cold white morning light, with light mist, air dust, and dreamy halos in the room. A large number of purple petals slowly fall in the air, with blurred petals in the foreground and background, creating a strong sense of spatial depth. The overall color palette is dominated by the black piano, silver-white long hair, light blue-purple gown, purple petals, and cold white window light, creating a high-end, dreamy, romantic, and quiet atmosphere.
