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 dark, gritty street fight alleyway from a manhwa comic. On the left side, extend the textured brick wall with rough patterns, adding more shadows and urban grime. On the right side, extend the chain-link fence, the dark alleyway opening, and silhouettes of distant city buildings at night. Maintain the perspective of the ground asphalt. High-contrast monochrome black and white manga ink style, sharp manga line-art, deep blacks, heavy shadows, intense action atmosphere.
