Soft Studio Portrait With Pink Device

Create a photorealistic vertical 2:3 studio portrait of an adult East Asian woman, early 20s, with {argument name="hair color" default="long slightly messy black hair"}, fair skin, a soft natural smile, and large black rectangular eyeglasses. She is seated or leaning slightly forward, shown from upper torso to head, turned three-quarters toward the left side of the frame while looking off-camera left. She wears a simple light gray camisole or lounge top with white shoulder straps, natural minimal makeup, soft pink lips, and a gentle relaxed expression. Her right hand holds exactly 1 object: a slim pastel pink handheld electronic device with rounded corners, a small circular button near the top, and two tiny indicator dots, held vertically near her cheek. Use a clean pale aqua-blue seamless background, soft diffused studio lighting, shallow depth of field, crisp facial detail, natural skin texture, realistic hair strands, and a fresh lifestyle/product-photography feel. Keep the composition airy with the head near the upper center, the hand and device on the lower left, and no text, logos, watermark, or extra props.
