Ultra-photorealistic cinematic sci-fi still. A female adventurer with subtle cybernetic overlay stands on the left, back-to-back with a towering steampunk mecha companion on the right. Both in confident contrapposto poses, looking directly at the camera. Full-body, open composition. Behind them is a dark ancient underground jungle tomb entrance with carved stone walls, mossy pillars, worn stairs, vines, ferns, broken ruins, humid mist, and dense greenery. The woman has an athletic figure with sun-tanned skin, subtle sweat, light grime, and faint scars. She has a fierce expression, full lips, and heavy-lidded eyes. Her hair is punk-inspired: braided with beads, shaved sides, and loose wind-tossed strands. She has a non-invasive cybernetic overlay: faint glowing blue circuit-like patterns, translucent HUD-style markings, and subtle metallic-light accents projected over her arm, shoulder, ribs, neck, and temple. The overlay follows the contours of her body and skin without replacing anatomy. She wears a weathered beige cropped tank top, faded blue-teal cargo pants, a tactical leather chest harness with brass buckles, a utility belt with pouches, rope, compass, climbing axe, dual thigh holsters, torn sash, fingerless gloves, arm wraps, bandages, and heavy dusty brown leather boots. The mecha has detailed retro-futurist 1800s steampunk armor with brass and iron plates, exposed pistons, gears, rivets, hydraulic joints, glowing blue optics, cables, scratched metal, and jungle grime. Warm golden sunlight filters through the jungle canopy with volumetric rays, mist, wet stone reflections, and sharp shadows. Slightly desaturated sepia cinematic grading with blue-glow contrast. gritty realism, highly detailed skin, fabric, leather, brass, and metal. Shallow depth of field, sharp subjects, softly blurred background
