Ronin walks through broken spears at dusk

Original prompt

A lone samurai in a tattered black kimono walks slowly across a deserted battlefield at dusk, the ground littered with broken spears and burning banners; his sword drips with rain as thunder rumbles in the distance, and a sudden gust of wind sends ash swirling around him—camera tracks from behind in a steady dolly shot, then shifts to a close-up of his determined eyes under a straw hat, warm orange sunset light colliding with cold blue storm clouds, medium telephoto lens, cinematic contrast; the style is realistic historical drama with an epic, solemn mood.
