Reference: use the photo I uploaded for the young man.

Subject and pose: a young man crouched in a dramatic, low lunge inside a huge industrial warehouse hall. One hand presses hard against the floor in the foreground, his body leans forward in a dynamic attacking stance, his face shows intense focus.

Creature: a glossy black alien symbiote bursts out of his back: long, fluid tendrils, sharp teeth, a wide and menacing grin, and an organic, liquid texture. Give the tendrils a subtle sense of moving energy.

Wardrobe: a dark modern outfit (black shirt, fitted trousers, boots), with realistic folds in the fabric.

Lighting: strong cinematic light from above, bright ceiling panels producing lens flares, volumetric beams, reflections on the polished concrete floor; high-contrast film lighting with dramatic shadows.

Atmosphere: moody haze in the air.

Camera and finish: shallow depth of field, ultra-sharp focus, hyper-detailed skin texture, photorealistic rendering, cinematic color grading, in the style of a still from a blockbuster movie, 8K resolution.

Format: vertical, 4:5 aspect ratio.
