A close-up portrait featuring a dark metallic texture, with an improved Stormtrooper helmet suspended against a pure black background. The surface is covered in carbon fiber texture, while the black mirrored visor reflects cold light points. The breathing grill and side communicator present precise mechanical details, and the top of the helmet has a subtle mesh texture. The bottom fades into deep shadows, conveying a cold, ruthless imperial military aesthetic and a sense of futuristic technology.
