Create a double-exposure portrait of a Japanese courtesan that blends abstract, artistic textures, such as splashes of watercolor and light effects, with sharp geometric shapes and lines. The portrait should capture the essence of the woman's personality, adding a dreamy or mysterious feel through the use of abstract patterns, and adding a modern, stylish look through the use of geometric shapes overlapping or merging with his form. There can be flowers on top of geometric lines. The combination of these elements should symbolize the multifaceted nature of the human spirit and the intersection of tradition and modernity, and should evoke a sense of complexity and depth.
