A dramatic masterpiece webtoon background illustration of a South Korean school classroom, high-angle slightly perspective view from the front-left side. In the background, there is a realistic regular-sized green chalkboard on the beige wall, completely blank and empty for text. In the classroom, several high school students/bullies are sitting at their wooden desks, turning around in complete shock, terror, and amazement, looking towards the camera with wide eyes and frightened faces. The teacher's podium is gone, leaving an open empty area on the right side of the frame. The art style must perfectly match the exact sharp lines, muted color choices, and dark intense mood of the manhwa "High School Conquest" (고교정벌). Crisp cell shading, atmospheric lighting with soft shadows.
