Photorealistic Assassin in a Spacecraft Corridor

Hyper-realistic, photorealistic depiction of a stealthy assassin in a sleek spaceship corridor. A lithe operative wearing a matte-black, form-fitting stealth suit with subtle reflective panels, an integrated HUD on the helmet visor, and a compact silenced pistol holstered at the hip. The visor reflects a starfield and the neon-lit corridor. The environment features chrome panels, exposed cables, and blue-purple neon accents along the walls. A large viewport reveals space and distant stars beyond. Cinematic, slightly low-angle composition with shallow depth of field focusing on the assassin's intense, calm gaze. Rim lighting outlines the silhouette; subtle breath vapor in cold air; realistic textures: scratched metal, fabric weave, glass reflections, and faint lens flares from digital displays. 8k, ultra-detailed realism. Non-graphic, no gore.
