A realistic illustration of a Black Mercedes Benz AMG GTR cruising through the drenched streets of Berlin, Germany. It's noon, and the cityscape is under a moody, overcast sky with raindrops cascading down in a gentle pattern, reflecting the intricate details of the architecture in a shimmering dance on the wet road. The car's sleek bodywork glistens under the muted, diffused light, revealing the exquisite craftsmanship of its design. Lush green trees lining the boulevard sway softly in the rain. Passersby, shielded under vibrant umbrellas, add a splash of color to the otherwise monochrome scene. The image captures an 8K resolution with HDR quality, using Octane Render for a hyper-realistic finish, with an aspect ratio of 16:16.
