Outpainting panorama, wide 16:9 webtoon preview banner. Tight medium shot. In the center, the character from the reference remains COMPLETELY UNCHANGED: a man with short black hair, calm dark human eyes, wearing a tactical military vest, holding a silver Desert Eagle pistol near his face in the exact same pose. Completely replace the background behind him. Change the background into a modern gunsmith workshop. Directly behind his back, generate a white pegboard tool wall filled with various modern assault rifles, shotguns, and tactical firearms hanging on hooks. Below him, show the edge of a light-colored workbench table with disassembled weapon parts and screwdrivers. Expand this gun workshop environment horizontally to the left and right, maintaining a clean webtoon art style and matching the character's lighting.
