Epic cinematic 8k wallpaper of Ellen Ripley, with a determined and serious expression, inspired by the Alien movie. She's wearing a white, worn, and dirty tank top, depicted in a wide-angle action pose, captured in a half-body shot. Her forehead and cheeks glisten with sweat, emphasizing the intensity of the moment. The image is photorealistic, with a cinematic ambiance and movie-quality visuals enhanced by VFX post-production and RTX ray tracing lighting. Ultra-realistic and hyper-detailed, the scene is rendered in HD, HDR, with both 4k and 8k resolutions, as if shot on a vintage Mitchell BNC camera using Octane Render. The composition captures a sense of urgency and grit while maintaining the core atmosphere of the iconic character.
