动漫剪影叙事海报

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.

基于 {argument name="theme" default="进击的巨人"}，自动生成一张具有收藏价值的史诗级叙事海报：使用 {argument name="character" default="戴着红色围巾的米卡莎·阿卡曼"} 的侧面剪影作为外轮廓。在剪影内部，有机地生长出一个最契合主题的完整世界。希干希纳区燃烧的街道倒映在她的眼中；少年艾伦·耶格尔的笑容在烟雾中逐渐消散；阿卡曼家族的纹章如水印般隐约浮现；最终战场的阵阵海风带走了所有记忆；倒计时沙漏的碎片化作飘落的樱花，随后消散为灰烬。

整体构图不应是简单的拼贴，而应是精致的剪影叙事合成。它应具备双重曝光的联想效果，但更倾向于电影海报与梦幻水彩插画的融合。运用柔和的空气透视、轻柔的雾气过渡、纸张纹理、带有笔触感的白边以及大面积的留白。布局应显得克制、高级、宁静、宏大、神圣、怀旧、诗意且具有传奇色彩。

调色板：{argument name="colors" default="深红色与灰色的融合、柔和的粉色、深邃的黑曜石色"}。

所有元素——风格、色彩、场景、材质——必须自动适配主题，每一个细节都与主题紧密相连。一眼即可精准识别。避免杂乱、生硬的拼贴、模板化的背景或廉价的奇幻素材。
