A Japanese woman in her 20s is holding a smartphone in both hands and smiling gently while gazing at the screen, her long straight hair flows beautifully from her shoulders to her chest, her eyes are relaxed and the corners of her mouth are turned up in a natural smile, her thumbs are operating the screen, her gaze is focused on the smartphone screen, she is in a relaxed position with her head tilted slightly, her body is facing forward and her upper body is leaning slightly forward, her white cropped short-sleeved cotton T-shirt simply shows off her body lines and exposes her navel, she is wearing denim shorts, the background is completely white, the style is minimalist modern, there is soft front lighting, and the composition is a close-up from the bust to the waist, with the subject in the center.
