Фитнес-портрет у утреннего окна

A commercial lifestyle portrait of a young adult East Asian woman standing before a modern high-rise apartment's floor-to-ceiling glass window. Her body is angled roughly 150° away from the camera, hands naturally resting on the window frame as she leans slightly forward, head looking back over her shoulder with a calm, confident, and gentle expression. She has a slender, athletic build with long legs, one foot lightly resting on tiptoe in a light posture. She wears [a black sports bra with a cross-back X-strap design and black high-waisted athletic compression shorts] in matte technical fabric without logos. Her deep brownish-black hair is styled in a loose, natural messy bun with subtle stray strands. Outside, a cool-toned urban skyline is softly blurred with gentle window reflections. Warm morning sunlight streams in around [9 AM], producing delicate rim lighting along her shoulders, back, hips, and legs, paired with soft natural interior shadows and no HDR. Low-saturation, creamy color grading in the visual aesthetic of [Lululemon, Alo Yoga, and Nike Women campaigns].
