课堂自然抓拍照片，白板上动漫素描

Use my reference image for face attachment 

A realistic, candid smartphone photograph with subtle film grain, taken inside a classroom. A large whiteboard dominates the scene. On the whiteboard is a hand-drawn sketch of {argument name="anime character" default="Nami from One Piece"}, drawn entirely with a blue whiteboard marker, loose but confident linework, clearly recognizable anime proportions. Nami is depicted wearing a deep-neckline tank top, stylized but appropriate for a casual sketch. 

Standing beside the whiteboard is Sadie Sink , casually posed and smiling toward the camera, as if proud of the drawing. She is wearing a deep-neckline tank top and fitted jeans. Natural posture, relaxed confidence. Classroom lighting is soft and slightly uneven, typical of overhead fluorescents. The photo has slight motion imperfections, realistic smartphone dynamic range, mild blur at the edges, and authentic film grain. Color tones are neutral with a hint of warmth. The overall mood feels spontaneous, informal, and behind-the-scenes.
