16:9 horizontal, realistic-photo-based advertisement banner / YouTube thumbnail. Bright, airy, and clean design with plenty of white space. Pastel accent colors (soft mint, pale yellow) on white/off-white background. Natural sunlight lighting from the left. The main subject is a candid photograph of a young woman (mid-20s, East Asian, natural skin texture with soft pores, shot on a DSLR with a 50mm lens), smiling gently while looking slightly upward with confidence. She wears a casual white linen blouse and holds a smartphone in one hand, earbuds in her ears, suggesting an online conversation. Background is a bright, airy room with large windows, soft curtains, and a small desk with a laptop and a cup of coffee. Text is embedded in the image: top right corner, title "【期間限定】" in bold, medium gray (subtle). Center, largest and boldest, white text with thick dark gray outline (high contrast): "無料体験 レッスン". Below it, smaller white text with outline: "まずは話してみよう！". All text in Japanese, no logos, no watermarks, no English decorative text. Layout: person on the right side, facing left; text block on the left and center. Ensure the text does not obscure the face. Photorealistic quality, natural skin texture, high fidelity photography style.
