Create a image of a Shiba Inu dog dressed as a Japanese samurai in pixel art style, wearing a traditional kasa hat, green cloak, and dark armor, holding a katana with both paws. The dog has a cute, determined expression with its tongue slightly out. The background features a cherry blossom tree in full bloom, a blue sky with white clouds, and floating petals. Use a limited 16-bit color palette, dithering, and clean pixel outlines for a retro game aesthetic. Emphasize charm and nostalgia with detailed pixel shading and a vibrant yet cohesive color scheme.
