Epic cinematic 8k wallpaper of Ellen Ripley, her face determined and intense, from the Alien movie, clad in a weathered and grimy tank top, captured from a wide angle in an action pose, focusing on her sweat-dappled forehead and cheeks in a half-body shot. The image is photorealistic and cinematically styled, achieved through advanced VFX post-production and RTX ray tracing lighting. The scene is ultra-realistic and hyper-detailed, presented in HD, HDR, 4k, and 8k resolution, as if shot on a legendary Mitchell BNC camera using Octane render. The atmosphere is tense and immersive, exuding a sense of imminent danger and resilience.
