Mechanical Keyboard Themed Art Poster Prompt

A 16:9 landscape-composition art poster themed around mechanical keyboards. The left side of the frame occupies one quarter of the width, showing a close-up half-body portrait of [{argument name="character name" default="character name"}], with the person shown from the shoulders up, an intense gaze, the edges softly feathered to blend naturally into the background. Light particle effects and color-gradient haze float around the person. The right side of the frame occupies three quarters of the width; the upper portion presents an artistic keycap display: 5 to 7 exquisite mechanical-keyboard keycaps scattered in an elegant arc in the air, each showing a different angle and detail. The keycap color scheme is drawn from the character's [{argument name="primary color 1" default="sakura pink"}], [{argument name="primary color 2" default="cream white"}], [{argument name="accent color" default="coral red"}]. The keycap surfaces are printed with [{argument name="theme element" default="a chibi silhouette of the character / an exclusive icon / a gradient texture"}], rendered in [{argument name="keycap material" default="frosted PBT / translucent resin"}] material. Beside each keycap floats a Chinese artistic-lettering label, using the font Zcool High-End Black or Youshe Title Black, reading "{argument name="label 1" default="樱花粉主键"}", "{argument name="label 2" default="渐变镀膜"}", "{argument name="label 3" default="双色透光"}", "{argument name="label 4" default="角色印刷"}", "{argument name="label 5" default="金属空格"}" — craftsmanship notes like these, with the text carrying a slight glow effect and outline. The lower portion of the right side of the frame is evenly divided into three sections: the left panel shows a full top-down flat-lay of the complete mechanical keyboard, [{argument name="keyboard layout" default="68-key compact layout / anodized aluminum-alloy base"}], labeled at the bottom in Chinese "{argument name="left-panel label" default="完整配列"}"; the middle panel shows a macro close-up of the side of the keyboard, emphasizing craftsmanship detail and material layering under the light, labeled at the bottom "{argument name="middle-panel label" default="匠心工艺"}"; the right panel shows the keyboard styled in a [{argument name="scene 1" default="cozy desk scene / café tabletop / workbench"}] setting, with lifestyle props such as [{argument name="props" default="a coffee cup / a potted plant / a notebook"}], labeled at the bottom "{argument name="right-panel label" default="生活美学"}". The overall background uses a [{argument name="background effect" default="ink-wash bloom / particle light effect / gradient frosted mist"}] effect, with the main color gradient drawn from the character transitioning from [{argument name="color 1" default="color 1"}] to [{argument name="color 2" default="color 2"}], darker on the left and lighter on the right. Delicate light spots and flowing color mist are scattered through the background, creating a [{argument name="mood" default="dreamy and soft / cyber-tech / vintage elegance"}] mood. At the bottom center of the frame is a large title text: "{argument name="main title" default="角色名称主题定制键盘"}", in bold Chinese artistic lettering with a metallic texture or glow effect. There are no obvious dividing lines in the frame; each area transitions naturally through light/shadow interplay and depth-of-field layering. The overall look has the visual quality of a fashion-magazine cover, with moderate color saturation, rich layering, combining both artistry and product-display function. 4K ultra-high-definition resolution, 16:9 landscape composition, with visual impact suited for social-media sharing.
