Prompt

A 16:9 landscape-format artistic poster with a mechanical keyboard theme. The left side occupies one quarter of the width, showing a half-body close-up portrait of [{argument name="人物角色名称" default="人物角色名称"}], with the character shown from the shoulders up, eyes full of tension, and softly feathered edges that blend naturally into the background. Light-effect particles and color-gradient mist surround the character.  The right side occupies three quarters of the width. The upper section presents an artistic keycap display: 5 to 7 exquisite mechanical keyboard keycaps are arranged in an elegant curved arc and scattered in midair, each keycap shown from different angles and with different details. The keycap color scheme is derived from the character’s [{argument name="主色调1" default="樱花粉"}], [{argument name="主色调2" default="奶油白"}], and [{argument name="点缀色" default="珊瑚红"}]. The keycap surfaces are printed with [{argument name="主题元素" default="角色Q版剪影/专属图标/渐变纹理"}] and rendered in [{argument name="键帽材质" default="PBT磨砂/树脂透光"}] material. Beside each keycap, flowing Chinese artistic text labels use Zhongchuang High-End Black or YouShe Title Black, with content such as "{argument name="标注1" default="樱花粉主键"}", "{argument name="标注2" default="渐变镀膜"}", "{argument name="标注3" default="双色透光"}", "{argument name="标注4" default="角色印刷"}", and "{argument name="标注5" default="金属空格"}" to indicate craftsmanship details, with a slight glow effect and outline.  The lower half of the right side is evenly divided into three sections: the left panel shows a front-facing flat lay top view of a complete mechanical keyboard, [{argument name="键盘配列" default="68键紧凑配列/铝合金阳极氧化底座"}], with the Chinese label "{argument name="左格标注" default="完整配列"}" at the bottom; the middle panel shows a macro close-up of the keyboard’s side, emphasizing craftsmanship details and material layering under the light and shadow, with the label "{argument name="中格标注" default="匠心工艺"}" at the bottom; the right panel shows the keyboard styled in an atmospheric scene in [{argument name="场景1" default="温馨书桌场景/咖啡厅桌面/工作台"}], with everyday props such as [{argument name="道具" default="咖啡杯/绿植/笔记本"}], and the label "{argument name="右格标注" default="生活美学"}" at the bottom.  The overall background uses [{argument name="背景效果" default="水墨晕染/粒子光效/渐变雾面"}] effects, with the main color tone transitioning from [{argument name="颜色1" default="颜色1"}...
