A stunning epic cinematic 8k wallpaper featuring Ellen Ripley from the Alien movie, her face determined and serious. She is clad in a distressed and dirty white tank top, captured in an action pose, half-body shot. Her forehead and cheeks glisten with sweat, presented in a photorealistic and cinematic style. The scene is rendered with movie-quality visuals, enhanced through VFX post-production and RTX ray tracing lighting. This ultra-realistic, hyper-detailed image is in HD, HDR, 4k, and 8k resolutions, as if shot on a classic Mitchell BNC camera. With a slight creative twist, the environment hints at an industrial space setting with soft shafts of ambient light piercing through grates, utilizing Octane Render to enhance texture and depth.
