Surréaliste Brutalist Portrait Avec Kinetic Chrome Orbits Prompt Dans JSON

A highly detailed JSON prompt for Nano Banana Pro to create a hyper-realistic, surrealist portrait titled 'The Mental Orbit.' The subject stands in a dimly lit brutalist concrete chamber, surrounded by floating chrome spheres and jagged mirror fragments orbiting their head. The prompt emphasizes moody, directional lighting, rich texture (Kodak Vision3 500T film grain), and the physicality of the surreal elements.
