Ellen Ripley from the Alien movie, wearing an astronaut suit with her helmet on and the visor closed, looking determinedly upwards in a dynamic action pose. She's standing against the intricate interiors of the Nostromo space shuttle. This image showcases a sci-fi atmosphere using advanced Ray Tracing technology, with an ultra-detailed, hyper-realistic aesthetic. The chiaroscuro lighting adds depth and drama, complemented by overcast reflection mapping for a more immersive effect. Rim lighting highlights her stoic expression, capturing an epic, cinematic feel in 8k resolution. Achieving movie-quality realism, similar to a shot taken on a Canon 5D with octane rendering.
