Design an all Black full arm sleeve tattoo featuring a Japanese samurai in full armor with a katana, positioned dynamically. Surrounding the samurai are flowing cherry blossoms, a misty mountain range, and traditional Japanese structures like a pagoda. On the inner forearm, include a detailed Oni mask with sharp features and exaggerated shading. Use dark, dense black ink to create depth, with smooth transitions between the elements, blending the samurai, blossoms, mask, and mountains into a cohesive, flowing design tattoo idea
