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 menacing close-up of a juvenile delinquent from a Korean manhwa comic. Extend the character's shoulders, dark jacket, and light-colored undershirt outwards to the left and right edges. Continue the solid, minimalist grey background with a subtle manga screentone texture overlay. High-contrast monochrome black and white manga ink style, sharp manga line-art, deep blacks, heavy dramatic shadows.
