表情包最容易翻车的地方不是画得丑，而是十五张放在一起像十五只不同的狗。原因很简单：每写一张新图就重写一遍角色描述，模型每次都在重新理解「圆脸柴犬」长什么样。正确顺序是先锁角色，再批量换情绪。下面 15 条全部围绕同一只圆脸柴犬展开，前两条建立标准，中间十一条按情绪强度推进，最后两条解决成套输出与动感。
一、成套的前提是角色可复现
一张表情包能不能用，看的是它在聊天窗口里够不够清楚；一套表情包能不能用，看的是它们摆在一起像不像同一个角色。这两件事的解法完全不同：前者靠粗轮廓和高对比，后者靠固定的角色描述与固定的构图。
所以别急着写情绪词。先把头部角度、耳朵形状、口鼻颜色、项圈颜色这四项定下来，写成一段固定文本。后面每一条提示词都从这段文本开始，只在结尾追加情绪。这样即使模型有随机性，轮廓也不会跑太远。
二、角色锁定：三视图与表情基线
这两条不参与最终交付，它们是标尺。三视图用来确认比例，基线用来确认五官位置。做完之后把它们和任意一张成品并排看，能立刻判断出成品有没有跑偏。
01 · 三视图：把比例钉死
Character sheet of a round faced shiba inu sticker mascot, front, side and back view, [fur tone] coat with a cream muzzle, tiny black nose, [collar color] collar, flat white background, even light, minimal outline, consistent proportions怎么用：[fur tone] 填 warm tan，[collar color] 填 soft red，这两个值后面全部沿用。三个视角要等宽排列，用横幅比例。如果三个视角的耳朵高度不一致，在句首补 same character, same proportions 再出一次。
02 · 表情基线：只做中性脸
Baseline expression of the same shiba, mouth a tiny w shape, eyes two dots with single highlights, ears upright, [head angle], soft front light, [backdrop], head and shoulders only, clean vector edges怎么用：[head angle] 填 facing the camera，[backdrop] 填 pale gray。这张必须完全中性，连 happy 都不能写，否则后面所有情绪的基准都会偏。头肩构图，头部占画面一半左右，方形画布，方便后面统一裁切。
三、日常情绪：先用六张打底
聊天里出现频率最高的其实是弱情绪：有点开心、有点委屈、有点疑惑、有点无语、有点困、有点馋。这六张做扎实，一套表情包就有了八成使用场景。强情绪留到下一节，别一上来就画到最满。
03 · 开心：月牙眼
Cheerful shiba sticker, eyes curved into crescent arcs, mouth open with a small pink tongue, [cheek detail], both front paws lifted, [outline weight] white edge, plain [backdrop] background, square canvas怎么用：[cheek detail] 写 two rosy dots，[outline weight] 填 medium，[backdrop] 填 warm white。月牙眼要写 curved into arcs，写 closed eyes 会画成睡着。舌头别写 long tongue，长度一过就变哈士奇。
04 · 委屈：眼睛里要有水
Slightly hurt shiba, glossy eyes with a wet lower lid, brows angled up at the inner corner, [mouth shape], ears half folded, dim [light quality] from above, pale blue backdrop, tight head crop怎么用：[mouth shape] 填 a small trembling pout，[light quality] 填 soft light。泪光靠 wet lower lid 这一个词就够，写 crying 会直接变成大哭。耳朵半折是委屈的关键信号，删掉之后只剩一张面无表情的脸。
05 · 疑惑：歪头十五度
Confused shiba tilting its head to [tilt side], one ear up and one ear down, mouth a short slanted line, a small [symbol] above the head, flat [backdrop] background, even lighting, sticker composition with white edge怎么用：[tilt side] 填 the right，[symbol] 填 question mark，[backdrop] 填 off white。歪头角度写 fifteen degrees 比写 tilt 更可控。头顶符号只放一个，且要小，符号一大就抢了表情的注意力。
06 · 无语：半月眼
Deadpan shiba, eyes reduced to two flat half circles, mouth a straight line pulled to one side, [brow state], head level facing forward, cool [backdrop] background, minimal shading, thick sticker outline怎么用：[brow state] 填 one brow slightly raised，[backdrop] 填 light gray。半月眼的上沿要平，写 half closed eyes 常常得到困倦而不是无语。这条几乎不需要阴影，去掉 shading 反而更像贴纸。
07 · 困：张嘴打哈欠
Sleepy shiba mid yawn, mouth stretched wide into an oval, eyes squeezed shut, [tear at the eye], head tilted back, night [light source] from the side, deep [backdrop] tone, soft edges, cozy mood怎么用：[tear at the eye] 写 a tiny tear at the outer corner，[light source] 填 lamp light，[backdrop] 填 muted navy。嘴形要写成 oval，写 open mouth 容易画成吼叫。深色背景在这套里只用这一张，用来区分时段。
08 · 馋：盯着看
Hungry shiba staring at [food item], a thin drool line from the corner of the mouth, pupils turned toward the food, [ear reaction], warm kitchen light, blurred pale gray backdrop, close three quarter view, glossy nose highlight怎么用：[food item] 填 a grilled sausage，[ear reaction] 填 ears perked forward。口水只画一条细线，写 drooling 会糊成一大片。食物要虚化，写清楚反而分散注意力。
四、强情绪：夸张但不失真
强情绪靠形变，不靠加元素。眼睛放大、嘴巴拉长、耳朵后压，这些都是形变；爆炸线、汗滴、怒符是添加物。添加物多了画面会脏，也更难和白底贴纸兼容。这一组尽量把力气花在五官比例上。
09 · 生气：鼓脸加气团
Angry shiba puffing its cheeks, brows pressed down into a hard V, [steam shape] rising from both sides of the head, mouth a tight upside down u, [backdrop] background, flat colors, bold outline, centered head怎么用：[steam shape] 填 two small cloud puffs，[backdrop] 填 pale yellow。鼓脸要写 puffing cheeks，光写 angry 只会得到皱眉。气团放在头两侧而不是头顶，头顶会顶到画布边缘。
10 · 震惊：瞳孔缩小
Shocked shiba, pupils shrunk to tiny points, eyes wide with visible whites, mouth a small open o, [fur reaction], a short motion line above the head, stark [backdrop] background, high contrast, square sticker怎么用：[fur reaction] 填 fur standing up along the back，[backdrop] 填 bright white。震惊的核心是眼白，提示词里必须出现 visible whites。动作线只留一条短线，多了会变成漫画分格。
11 · 得意：抬下巴
Smug shiba with chin lifted, one eye half closed in a sidelong glance, mouth a crooked smirk, [accessory], chest pushed out, dramatic [light direction], gradient [backdrop], low camera angle, confident pose怎么用：[accessory] 填 tiny black sunglasses pushed up on the forehead，[light direction] 填 side light，[backdrop] 填 warm gray。下巴抬高配合低机位才有俯视感，只写 smug 通常不够。墨镜别戴在眼睛上，戴上就看不见表情了。
12 · 加油：握拳前伸
Encouraging shiba with one paw clenched and pushed toward the camera, [expression], body leaning forward, short [motion lines] behind the fist, bright [backdrop], full head and paw, dynamic perspective怎么用：[expression] 填 determined eyes and a closed grin，[motion lines] 填 speed lines，[backdrop] 填 light mint。拳头朝镜头会产生透视放大，记得写 dynamic perspective，否则手会显得很短。这条适合做群聊里的打气图。
13 · 比心：两只爪子拼一个心
Shy shiba making a heart shape with both front paws, [heart placement], eyes looking away, faint blush on both cheeks, soft [light quality], pastel [backdrop], centered square frame, rounded outline怎么用：[heart placement] 填 the heart held at chest level，[light quality] 填 diffused light，[backdrop] 填 pale pink。爪子拼心对手型要求高，一次多出几张再挑。眼神要偏开，直视镜头会显得太主动，害羞感就没了。
五、成套输出：排版与动感
单张过关不等于整套成立。真正交付前还有两件事：把十五张排在一起看边框是否统一，以及给其中几张加一点动态暗示，让它们在聊天里更抓眼。这两步用提示词也能做，不必全靠后期。
14 · 九宫格预览
Grid layout of nine shiba stickers on one canvas, [grid order], identical white border on every tile, consistent character and palette, thin [divider] lines, neutral gray background, catalog presentation怎么用：[grid order] 填 three rows of three，[divider] 填 light gray。这条只用来做总览图，别指望它一次生成九种准确情绪。实际用法是先排出九宫格，再逐格替换成单张成品。边框不统一时，回看第一条的三视图重出。
15 · 动感：残影与抖动线
Shiba sticker with motion, head shaking side to side, two faint [ghost copies] offset behind, [motion marks] at the temples, crisp main silhouette, plain [backdrop], thick white edge, high contrast flat color怎么用：[ghost copies] 填 translucent afterimages，[motion marks] 填 short vibration lines，[backdrop] 填 white。残影透明度要低，写 strong ghost 会糊成三只狗。主线稿必须保持清晰，否则缩到聊天尺寸就认不出表情了。
六、通用出图技巧
- 把角色描述放在提示词最前，情绪词放最后。顺序反了，模型会先按情绪重塑造型，脸型就保不住。
- 所有图统一用方形画布，头部居中，后期裁切和排版都省事。
- 白边不要靠后期加，提示词里写 white edge 让模型一起画，边缘会更贴合轮廓。
- 一套里最多两张用深色背景，其余保持浅底，否则聊天窗口里会显得花。
- 情绪强度靠五官比例调整，不要靠堆符号；符号只做提示，不做主体。
- 出完一套先缩到手机聊天尺寸看一遍，看不清的表情直接重做，别留到发布后再说。
七、常见问题
问：为什么每张的耳朵形状都不一样？
答：耳朵是模型最容易自由发挥的部位，因为它在描述里通常只有一句 ears upright。解决办法是把耳朵写具体，比如 two triangular ears with rounded tips，并且固定在角色描述段里，不要每条重写。实在不稳，就固定一个头部角度，减少变量。
问：白边总是粗细不一，能修吗？
答：提示词里给的 outline weight 只能约束大致范围，真正的统一要靠后期统一描边。做法是先抠出主体，再用同样的像素值向外扩边。生成阶段只要保证背景干净、轮廓清晰，后期就很好处理。
问：一套十五张会不会太多？
答：平台上传通常有数量上限，实际使用中八到十二张就够覆盖日常。建议先做六张高频情绪试水，看使用数据再补。剩下的名额留给节日或节点款，比一次做满更灵活。
八、小结
表情包的门槛不在画技，而在纪律：角色描述不改、构图不改、边框不改，只改情绪。守住这三条，十五张自然像一套。想要更多角色类的写法，可以看卡通形象提示词合集；需要按风格检索，AI 绘画分类总览里都有归类。
