Epic cinematic 8k wallpaper of Ellen Ripley with a determined and serious expression, inspired by the Alien movie. She is wearing a worn, dirt-streaked white tank top, captured in a wide-angle, dynamic half-body action pose. Her forehead and cheeks glisten with sweat. This photorealistic image is rendered with cinematic movie quality, featuring cutting-edge VFX post-production and RTX ray tracing lighting. The ultra-realistic, hyper-detailed scene is depicted in HD, HDR, and shot on a Mitchell BNC camera with Octane Render, presented in stunning 8K resolution. Subtle creative elements include a background hinting at a futuristic spaceship interior with dim, ambient lighting, enhancing the intense atmosphere.
