Epic cinematic 8k wallpaper of Ellen Ripley from the Alien movie, face determined yet apprehensive, wearing a tight-fitting tank top, wide angle, dynamic action pose, half-body shot, beads of sweat on her forehead and cheeks, close-up, centered composition, her back pressed firmly against the cold, metallic wall of the Nostromo space shuttle. She's in a dimly lit room, sci-fi elements prevalent, utilizing Ray Tracing with subtle rim light highlighting her figure, ultra detailed with highest quality detailing, delivering a cinematic and movie-esque presence. The atmosphere is stoic and cinematic, with dark, moody tones, capturing lumen reflections and ambient lighting in 4k. It's inspired by high-fashion sense akin to Vogue, with Rembrandt lighting creating high contrast. The focus is shallow but evocative, utilizing RTX ray tracing lighting for ultra-realism, rendered with octane for an 8K resolution finish.
