A hyper-realistic depiction of a sleek Black Mercedes Benz AMG GTR set against the historic streets of Berlin, Germany. It's midday under a cloud-laden sky, with raindrops creating a shimmering layer on the car's polished surface. The wet cobblestone streets reflect the car’s silhouette with exquisite clarity. An array of vibrant autumn leaves is subtly scattered on the ground, adding a splash of color. Streetlights and the faint architecture of Berlin’s iconic buildings form a dramatic backdrop, enhanced by a soft focus that contrasts the ultra-detailed texture and shine of the car. Captured in 8K, HDR, utilizing Octane Render techniques to emphasize depth and realism, the scene conveys both the elegance of the vehicle and the atmospheric ambiance of a rainy Berlin.
