Epic cinematic 8k wallpaper featuring Ellen Ripley with a determined expression, inspired by the Alien movie. She is clad in a highly detailed, ornate space suit, with beads of sweat on her cheeks and forehead. Her beautifully symmetrical face is complemented by her strong stance. The scene is set within the Nostromo's intricate space shuttle interiors, exuding a sci-fi aura. The use of ray tracing and overcast reflection mapping enhances the ultra-realism and detail quality, achieving a photorealistic effect. The image resembles high-quality promotional art, with VFX post-production, RTX ray tracing lighting, and the impression of being shot on a Canon 5D in 8K resolution.
