A hyper-realistic depiction of a sleek black Mercedes Benz AMG GTR parked on a cobblestone street in Berlin, Germany, under a dramatic overcast sky. It's noon, and the soft patter of rain droplets creates a mirrored sheen on the car's pristine surface and the wet cobblestones. The cityscape is visible in the background with iconic Berlin architecture, blurred by atmospheric mist. The reflective puddles capture the city lights and passing shadows, accentuating the contrast between the car's lustrous body and the subdued urban environment. Captured in ultra-detailed 8K, the image boasts high dynamic range and is rendered with Octane technology, bringing an immersive depth to the scene. Subtle creative touches, such as streaks of raindrops on the windows and a light fog forming from the asphalt's heat, enhance the realism, while the car's bold contours and sophisticated elegance remain the focal point of this captivating composition.
