Design a poster that captures the essence of traditional Japanese tattoo art, featuring a majestic koi fish swimming upstream, surrounded by vibrant waves and blooming cherry blossoms. Incorporate bold lines and intricate details typical of ukiyo-e prints, emphasizing the contrast between the flowing water and the dynamic movement of the fish. Use a rich color palette of reds, blues, and blacks to evoke a sense of depth and cultural significance, while integrating elements like swirling clouds and stylized motifs to enhance the overall composition.
