产品视觉 GPT Image 2 提示词：Anime Silhouette Narrative Poster

Based on {argument name="theme" default="Attack on Titan"}, automatically generate a collectible, epic narrative poster: use the side-profile silhouette of {argument name="character" default="Mikasa Ackerman with her red scarf flowing"} as the outer contour. Within the silhouette, let a complete world organically grow that best fits the theme. The burning streets of Shiganshina reflect in her eyes; young Eren Yeager’s smile fades within the smoke; the Ackerman bloodline crest appears subtly like a watermark; the sea breeze of the final battlefield carries away all memories; fragments of a countdown hourglass transform into falling cherry blossoms, then dissolve into ashes. The overall composition should not be a simple collage, but a refined silhouette-filled narrative synthesis. It should carry a double-exposure associative effect, yet lean more toward a fusion of cinematic poster and dreamy watercolor illustration. Use soft atmospheric perspective, gentle mist transitions, paper grain texture, white edges with brushstroke marks, and large areas of negative space. The layout should feel restrained, premium, quiet, grand, sacred, nostalgic, poetic, and legendary. Color palette: {argument name="colors" default="crimson blended with gray, muted pink, deep obsidian black"}. All elements—style, color, scenes, materials—must automatically adapt to the theme, with every detail strongly bound to it. Instantly recognizable at a glance. Avoid clutter, forced collage, template-style backgrounds, or cheap fantasy assets.
