Mechanical Keyboard Art Poster Prompt

A 16:9 horizontal art poster with a mechanical keyboard theme. The left quarter of the screen displays a close-up bust portrait of {argument name="character name" default="[Character Name]"}. The person is shown from the shoulders up, with intense eyes, and the edges are softly feathered to blend naturally into the background. Light effect particles and color gradient haze surround the person. The right three-quarters of the screen, the upper half, presents an artistic display of keycaps: 5 to 7 exquisite mechanical keyboard keycaps scattered in the air in an elegant arc, each showing different angles and details. The keycap color scheme is extracted from the person's {argument name="main color 1" default="[Main Color 1: e.g., Sakura Pink]"}, {argument name="main color 2" default="[Main Color 2: e.g., Cream White]"}, and {argument name="accent color" default="[Accent Color: e.g., Coral Red]"}. The keycap surface is printed with {argument name="theme element" default="[Theme Element: e.g., Character Q-version silhouette/Exclusive icon/Gradient texture]"}, rendered in {argument name="material" default="[PBT matte/Resin light-transmitting]"} material. Chinese artistic text annotations float next to each keycap, using ZaoKu GaoDuanHei or YouShe BiaoTiHei fonts, with content such as "Sakura Pink Main Key", "Gradient Coating", "Two-color Light Transmission", "Character Printing", "Metal Spacebar", etc., describing the craftsmanship. The text has a slight glow effect and outline. The lower half of the right side is evenly divided into three areas: the left grid shows a flat top-down view of the complete mechanical keyboard, {argument name="keyboard layout" default="[68-key compact layout/Aluminum alloy anodized base]"}, labeled "Complete Layout" in Chinese at the bottom; the middle grid shows a macro close-up of the keyboard's side, emphasizing craftsmanship details and material layers under light and shadow, labeled "Artisan Craftsmanship" at the bottom; the right grid shows the keyboard in an atmospheric setting in a {argument name="scene" default="[Cozy desk scene/Coffee shop table/Workbench]"}, with lifestyle props like {argument name="props" default="[Coffee cup/Green plant/Notebook]"}, labeled "Aesthetics of Life" at the bottom. The overall background uses a {argument name="background effect" default="[Ink wash blur/Particle light effect/Gradient matte]"} effect, with the main color transitioning from {argument name="color 1" default="[Color 1]"} to {argument name="color 2" default="[Color 2]"} extracted from the person, darker on the left and lighter on the right. Fine light spots and flowing color clouds are scattered in the background, creating a {argument name="atmosphere" default="[Dreamy and gentle/Cyber technology/Retro elegant]"} atmosphere. A large title text is centered at the bottom: "{argument name="character name" default="[Character Name]"} Themed Custom Keyboard", using bold Chinese artistic font with a metallic texture or glowing effect. The image has no obvious dividing lines; areas transition naturally through light, shadow, depth of field, and visual reality. The overall presentation has the visual quality of a fashion magazine cover, with moderate color saturation, rich layers, combining artistic and product display functions. 4K ultra-high definition resolution, 16:9 horizontal composition, suitable for social media visual impact.
