A beautifully elegant young Japanese woman in her 20s gazes naturally at the camera with a subtle smile. This is a shampoo advertising poster featuring a bottle of green shampoo. The background is a springtime, light blue lake backdrop, capturing the freshness and nature. She is wearing a white tank top, and her hair is fluffy, soft, and naturally flowing down. The photo has a film texture, with strong natural lighting and Fujifilm colors.
