Epic cinematic 8k wallpaper of Ellen Ripley from the Alien movie, her face resolute and intense, wearing a weathered and grimy white tank top, depicted in a dynamic action pose. The shot is a close-up, half-body view, capturing her forehead and cheeks glistening with sweat. Achieved with photorealistic, cinematic quality incorporating VFX post-production, and featuring RTX ray tracing lighting. The result is ultra-realistic with hyper-detailed imagery in HD, HDR, 4k, and 8k resolution, as if shot on a Mitchell BNC camera using Octane Render. Making her character even more compelling, there's a faint mist surrounding her, providing an aura of mystery and tension.
