Dynamic Samurai Katana Slash Poster

Theatrical animation style dynamic battle scene of [a Japanese samurai warrior] unleashing a powerful forward slash. Extreme low-angle perspective with exaggerated wide-angle depth, the katana blade thrusting toward the viewer with fine metallic reflections and a distinct hamon pattern. The warrior has a sharp, determined gaze with teeth clenched, hair and [haori] whipping violently in spiraling gale-force winds. The rocky ground shatters beneath his forward step, sending rock fragments and dust flying outward. A radiant [blue-white] slash arc slices across the air leaving a luminous trail. Background features desolate craggy mountain ridges beneath dense, swirling storm clouds. High-contrast dramatic lighting, cinematic motion blur, vertical poster framing. No text.
