Cinematic 8k wallpaper of Ellen Ripley from the Alien movie, dressed in an astronaut suit with the helmet on and visor closed, looking upwards in a determined action pose. She is standing amid the complex interiors of the Nostromo space shuttle, capturing the sci-fi essence with ray tracing techniques. The image is ultra detailed, showcasing chiaroscuro lighting and exceptional detail quality, achieving an ultra-realistic and epic look. It resembles promotional art with overcast reflections and hyperphotorealism, enhanced by rim lighting. The scene conveys a stoic and cinematic feel at 8k movie quality, similar to being shot on a Canon 5d with octane render techniques. Small creative elements include a subtle glow around her suit to emphasize the dramatic lighting and a slightly wider shot revealing more of the Nostromo's architecture, maintaining the core concept of a strong and iconic sci-fi visual.
