Martian Astronaut and Alien Exchange

A girl in a fully closed modern white spacesuit with a tinted visor stands on the surface of Mars. Red-orange rocky desert, dusty pinkish sky. Opposite her stands a tall humanoid alien_description in a tight-fitting bio-organic suit of silvery-pearl color. Realistic detailed anatomy. The girl is handing him an human_item. The alien is handing her a alien_item. The moment of exchange. Both are looking at each other with cautious curiosity. In the background: a landing module and a strange organic alien ship, a setting Martian sun, long shadows, dust in the air, cinematic epic lighting, 8k, photorealism.
