Create one polished, source-grounded creative image. Create a polished four-frame stylized 3D storyboard of clearly adult firefighters performing a fictional apartment safety drill. Frame 1 ALERT: alarm activates. Frame 2 CHECK: responder assesses a smoky doorway from a safe distance. Frame 3 EXIT: adults follow a lit route while staying calm. Frame 4 CALL: team gathers outside and contacts emergency services. Use original rounded character designs, consistent red protective gear without real insignia, clean arrows, restrained smoke, and readable labels ALERT, CHECK, EXIT, CALL. Educational tone, no flames touching people, injury, gore, or named animation-studio style. Use only original worlds, characters, products, and organizations. Every depicted person is clearly an adult aged 25 or older. Do not imitate a named living artist or reference an existing franchise, celebrity, public figure, brand, trademark, or logo. No sexualized framing, gore, deceptive official seals, unsupported real-world claims, watermark, or signature. Keep anatomy, object construction, repeated details, lighting, perspective, and requested layout coherent. Render only explicitly requested text and no accidental extra lettering.查看完整提示词

请规避繁复的细微纹理、过度的细节刻画、颗粒噪点、粗糙质感、斜向网格纹路、瓷砖式重复纹样、泥污类叠加效果，同时去掉多余的闪光特效。
弱化复杂纹理质感，优先保证画面表面顺滑均匀、轮廓线条粗实清晰、主体轮廓辨识度高。
相较于堆砌细节，更注重造型利落、留白恰当、构图规整，打造干净的画面观感。查看完整提示词
-#将图2，图3中的角色分别完整替换到图1的场景中，严格保持图1角色中角色身体姿态、面部表情、视线角度及所有细微动作分毫不差，服饰与图2和图3分别保持一致，图2在左，图3在右。需确保替换后角色与场景光照、透视关系及构图氛围完全融合，避免产生不协调的图层叠加感或透视错误。重点优化角色面部五官比例与对称性，特别是眼睛的透视与瞳孔高光位置需精确对应原图表情神态；同时细致处理手指结构与关节细节，防止出现多指、粘连或结构扭曲等常见崩坏问题。最终成果应为高度协调的二次元风格图像，人物线条清晰流畅，色彩过渡自然，无明显人工生成痕迹，呈现如原画师手绘般的整体质感。保证角色动作和表情保持不变。动作完全参考图一。

绘制一张以图一角色为主要参考对象的脸部特写画作。画面由多种不同时代的电子设备屏幕共同拼合而成，像一幅由屏幕组成的碎片化肖像拼贴。角色形象以图一为基础，保留她最具代表性的面部特征、发型、气质与白色面纱遮住眼睛。她端坐着，微笑着看向镜头，整体氛围神秘、安静、带有轻微科技感与注视感。画面主体是一张完整的人物脸部特写，但这张脸不是直接绘制在单一画布上，而是被拆分显示在多台电子设备的屏幕里。设备包括老年机、翻盖手机、早期智能手机、现代智能手机、MP4 播放器、BP机、掌上游戏机、小型数码播放器等。不同设备因为年代、屏幕材质和显示能力不同，画质存在差异：老年机和 BP 机屏幕分辨率较低，可能出现像素感、噪点、色偏、扫描线、低饱和度或显示残缺；翻盖手机和 MP4 屏幕略微模糊；现代智能手机屏幕更清晰、色彩更准确。
禁止:屏幕形状不规则，异形屏幕，三角形屏幕，圆形手机屏幕，漂浮屏幕，透明屏幕，科幻虚构屏幕，屏幕无边框，设备不符合现实，设备过度变形，手机弯曲，屏幕弯曲，文字乱码，文字过多，文字无法阅读，脸部被文字完全遮挡，屏幕之间完全无法拼合，拼贴后不成人脸，全部屏幕同一种设备，画面外围被设备铺满，没有留白查看完整提示词
以第一张三视图和第二张证实图为角色基础，第三四为同角色同人图，原型为在中国的哔哩哔哩视频网站的虚拟偶像“宣小纸不怕火”，个人主页为https://space.bilibili.com/3461582034045213。自动生成一张收藏版史诗叙事海报：巨大优雅的人物侧脸剪影作为外轮廓，剪影内部自动生长出最契合该主题的完整世界观、标志性场景、角色关系、象征符号、关键建筑、生物、道具与氛围。整体不是普通拼贴，而是高级的剪影轮廓填充式叙事合成，带有双重曝光式联想，但更偏电影海报与梦幻水彩插画融合风格；柔和空气透视，轻雾化过渡，纸张颗粒，边缘飞白与刷痕，大面积留白，版式克制高级，安静、宏大、神圣、怀旧、诗意、传说感强。风格、色彩、场景、材质全部根据主题自动适配，所有元素必须强绑定主题，一眼识别，不要杂乱，不要硬拼贴，不要模板化背景，不要廉价奇幻素材。画面中需自然加入专属签名“【宣小纸不怕火 】”，作为海报设计的一部分，位置低调但清晰，可放在左下角、右下角或标题附近，风格需与整体版式统一，像收藏版海报的作者落款或设计签章；签名字体精致、克制、高级，不可过大，不可破坏主体构图，不可显得突兀廉价。
