Masterpiece, best quality, ultra HD image, 4K resolution. A highly realistic anime-style young woman lying on a large, two-person bed at night, illuminated by soft moonlight streaming through a nearby window. Her expression is gentle and slightly surprised, with a captivatingly beautiful face and a serene demeanor. Her long, slightly wavy black hair, with hints of dark blue highlights, spreads out dynamically around her, cascading over the bed in soft, natural waves. The moonlight catches the subtle hues in her hair, adding depth and texture to its flow. Her body has a graceful, natural form, with perfectly balanced proportions. She is wearing an elegant, modest sleepwear outfit—perhaps a fitted, silky nightgown in a deep, calming color such as navy or burgundy. The fabric delicately clings to her figure, enhancing her beauty without revealing cleavage or being overly provocative. Her chest is realistically dynamic, lifted slightly due to her lying posture, avoiding unnatural sagging while still appearing natural and soft. The bed is large and luxurious, with crisp white pillows that contrast beautifully against the rich, dark tones of the comforter. The comforter is slightly disheveled, half-pulled back to reveal part of her body and the smooth white sheets beneath. The comforter features intricate, dark-colored patterns—perhaps in black or deep grey—with subtle, elegant designs that add richness without drawing attention away from her. The setting captures a cozy, intimate atmosphere of nighttime tranquility. The window is partially open, allowing cool moonlight to spill into the room, casting soft highlights and subtle shadows across her figure and the bed. The interplay of light and dark creates a cinematic, high-contrast effect, as if rendered in RTX-level quality. The textures of the sheets, comforter, and her hair are all vividly detailed, adding to the realism. The room is simple yet elegant, with a wooden nightstand (komodin) beside the bed. On it rests an unlit vintage lamp, a small vase of flowers, and a half-read book, subtly hinting at her personality. The perspective is top-down, as if viewed from the ceiling, showcasing her relaxed, natural pose and the full layout of the bed. The overall mood is calm, intimate, and visually stunning, with dynamic elements like her softly flowing hair and the slightly rumpled bedspread adding life and realism to the scene. Every detail, from the lighting to her expression, is designed to emphasize her beauty and the serene atmosphere of the night. mythp0rt
