"Design a dynamic and detailed horizontal background illustration in sumi-e ink painting style, where the main subjects are a crane and a turtle. The turtle should be interwoven with various shades of green, capturing its form with a sumi-e approach. The crane, in contrast, should be depicted in blacks, reds, and whites, with a divine and vivid presence. Both animals should be portrayed with a sense of movement and grace, reminiscent of the traditional techniques used by Katsushika Hokusai, combining a sense of the auspicious with artistic dynamism and delicacy."
