Cinematic 8k wallpaper featuring Ellen Ripley from the Alien movie, outfitted in her iconic astronaut suit with helmet on and visor closed. She stands confidently in an action pose, gazing upwards, surrounded by the atmospheric interiors of the Nostromo space shuttle. The scene is sci-fi inspired, with an ultra realistic touch achieved through Ray Tracing, constructed with the highest detail quality. The chiaroscuro lighting adds a dramatic flair, further enhanced by overcast reflection mapping for depth. The image is hyperphotorealistic and resembles epic promotional art, capturing every intricate detail with stoic elegance. Rim lighting highlights Ripley's figure, and the scene exudes movie quality, as if shot on a Canon 5D with Octane Render in 8K resolution. The aesthetic is intensely realistic, evoking the tense, adventurous spirit of the Alien universe.
