Generate a photorealistic portrait of a serene Japanese geisha. She should be depicted wearing a meticulously detailed, richly patterned traditional silk kimono with elegant designs such as cherry blossoms or cranes. Her face should feature the classic white oshiroi makeup, with precisely applied red lipstick and subtle, artful eye makeup. Her hair should be styled in an elaborate traditional nihongami updo, adorned with delicate kanzashi hair ornaments. The background should vividly portray a spring scene in Kyoto, featuring lush cherry blossoms in full bloom and hints of traditional Japanese architecture. Ensure the lighting is soft and natural, emphasizing the elegance and tranquility of the scene. The composition should be a medium shot, capturing her poised expression and the intricate details of her attire against the atmospheric backdrop.
