Ultra-Cinematic Winter Samurai Portrait

A highly detailed, structured prompt for generating an ultra-cinematic, photorealistic film still of a female samurai in a winter garden at night. It specifies constraints, output settings (4:5 portrait, cold color grade), and creative details, including a white ceremonial kimono, a katana raised overhead, and volumetric moonlight through falling snow, aiming for lethal elegance and feature-film realism.
