Outpainting, extend the canvas horizontally to 16:9 widescreen aspect ratio. Keep the central image completely locked and unchanged. Dynamically extend the sides of the frame. The scene is a continuation of a dramatic, menacing close-up from a modern Korean webtoon comic. Extend the character's wide shoulders and dark suit jacket to the left and right edges. In the background, seamlessly continue the intense, solid blood-red background texture with subtle splatters, specks, and grit particles. Maintain the highly detailed, high-contrast manhwa art style with sharp ink line-art and deep dramatic vertical hatching shadows.
