16:9 aspect ratio, horizontal YouTube thumbnail / social media banner. A photorealistic candid photograph of a young Japanese woman in her early 20s, slim build, smiling naturally while holding a smartphone in a bright cafe. She wears a casual white blouse and light cardigan. The background shows a sunlit cafe interior with soft greenery and wooden tables, natural daylight streaming in from a window, creating a clean, fresh atmosphere. She looks directly at the camera with a confident, friendly expression. The scene feels spontaneous, like a genuine moment captured on a DSLR (35mm lens). Lighting: bright, soft natural light, gentle shadows, high-key overall, with pastel blue and warm beige accents. Composition: woman positioned slightly right, looking towards camera. Text overlay: top left in large bold Japanese "オンライン英会話" (white with black outline), center in huge bold Japanese "【無料体験】" (white with black outline, very readable), bottom right smaller "まずは1回、気軽に話してみよう" (white). No logos, no English decorative words, no watermarks. All text is drawn accurately. The person is photorealistic, not illustration or 3D. Avoid any anime/cartoon style.
