Vinland Saga Thorfinn Storm Poster

Prompt

A dark, gritty cinematic anime poster in the style of a historical seinen manga cover, inspired by {argument name="series title" default="VINLAND SAGA"}. The composition is vertical and dramatic, with a lone young warrior resembling {argument name="character name" default="THORFINN"} standing on a jagged black rock at the edge of a stormy sea, seen from behind at full body. He wears a weathered brown-grey hooded tunic or cloak with a rough fur-trimmed collar, a belt at the waist, dark trousers, and worn leather boots. His posture is tense but reflective, his right hand holding a short dagger pointed downward, facing violent ocean waves and sea spray under a cold, overcast sky. Behind him and dominating the upper half of the image is a massive close-up side profile of his head and wet, tangled blond hair, rendered with dense ink-like linework and painterly shading, creating a layered double-exposure effect. On the left side, include 4 inset manga-style narrative panels stacked vertically: panel 1 shows a close-up of the same boy gripping a dagger; panel 2 shows him from behind facing a small group of armed men; panel 3 shows an intense close-up of his eyes; panel 4 shows him walking alone among gravestones or stone markers. Add visible typography integrated like a Chinese promotional poster: at the top left, small Japanese title text and the English text "VINLAND SAGA" with "YUKIMURA MAKOTO" beneath it; near the lower left, large distressed block letters reading "THORFINN" with smaller katakana beneath. Add multiple vertical Chinese quote lines in white along the left and right sides, with one emphasized phrase in muted gold. Use a desaturated palette of charcoal black, slate grey, steel blue, dirty white, and faded brown, with high contrast, mist, rain-speck texture, rough brushwork, and an epic melancholy atmosphere about renouncing violence and searching for peace. The overall look should feel like a premium character poster, moody, windswept, somber, and highly detailed.
