Epic cinematic 12K wallpaper of Ellen Ripley, face resolute and terrified, wearing a worn leather jacket and tight tank top beneath, wide angle, dynamic pose, high angle shot, with a mix of upper body and profile visible, emphasizing sharp cheekbones and determined jawline, heavy sweat on forehead and cheeks reflecting the dim fluorescent lights of the Nostromo space shuttle's cramped corridors, standing in a dimly lit, cramped, and decaying room with pipes and wiring visible behind her, sci-fi, ray-traced, high-dynamic range lighting, rim light emphasizing her stern expression, ultra-detailed 3D mesh, cinematic, movie-quality textures, nuanced skin and fabric rendering, high-contrast, shallow focus, rtx ray tracing lighting with subtle ambient occlusion, realistic lighting, and detailed materials, 8K and enhanced with AI-powered image denoising and comprehensive color grading, having a dark and moody atmosphere, and imbued with the sense of desperation and hopelessness that pervades the Alien franchise.
