A futuristic female astronaut stands at the entrance of a dark cave opening onto an alien world filled with floating clouds and jagged mountain peaks

Subject: A slender woman in a form-fitting white bodysuit integrated into her spacesuit, viewed from behind as she gazes out toward distant misty mountains. 

Clothing: High-tech sleek white exoskeleton suit with red accents on shoulders and helmet rim, visible mechanical joints at knees and elbows, glowing chest unit, full-face reflective visor helmet. 

Action: Standing still in a contemplative pose, facing forward into the distance, arms hanging loosely by her sides. 

Environment: Dark rocky cave interior framing a surreal landscape of towering dark peaks rising above sea-level clouds under an overcast sky with a large moon or planet visible through distant haze. 

Camera: Medium full-body shot from slightly low angle emphasizing silhouette and scale; shallow depth of field blurs background mountains for atmospheric effect. 

Lighting: Soft diffuse daylight filtering in from the cave mouth creating strong contrast between dark foreground shadows and bright misty horizon glow with subtle rim lighting on figure's suit edges. 

Style Details: Cinematic sci-fi rendering style, hyper-detailed textures mixed with painterly atmosphere emphasizing mood over realism; muted color palette dominated by greys whites blues accented with red highlights.
