Morning Bedroom Stretch Portrait

Create a realistic vertical lifestyle portrait of an adult Japanese woman waking up in a bright bedroom, seated on a white bed and stretching both arms across her face in a sleepy morning pose. She has hair_color shoulder-length wavy hair, slightly tousled, with soft flyaway strands catching the sunlight. Her face is fully hidden by her forearms and hands, with one arm crossing horizontally from the left and the other bent upward from the right; show natural fingers and relaxed hands near the center. She wears a simple top_color ribbed tank top with a scoop neckline. The composition is a close medium shot from chest to head, cropped at the upper arms, intimate but non-explicit, with realistic skin texture and natural body proportions. Background: a softly blurred sunlit bedroom with a large bright window on the left, pale curtains on the right, and white bedding at the bottom. Lighting should be warm morning window light, high-key, soft shadows, airy atmosphere, shallow depth of field, photorealistic detail, natural color grading, no text, no watermark, no extra people.
