Subject: Glowing cloud computing icon outlined by PCB circuit lines as the core subject, flowing 01 binary code filled inside the cloud body, vertical binary digital rain falling below the cloud body, middle part is future smart city buildings spliced from circuit textures and digital codes, bottom is circuit digital road extending into the distance and covered with binary characters. Scene: Virtual digital cyberspace scene, presenting the technical concept of cloud computing transmitting data to cities and empowering digital cities, buildings have mirror reflection effect at the bottom, overall is a futuristic digital network virtual space scene. Style: Tech concept vector illustration style, lines are in circuit line art texture, combined with cyber sci-fi design style, commercial design illustration style偏向互联网技术可视化。 Color tone: Overall unified cool blue tone, deep navy blue as background color, all glowing elements are high-saturation bright ice blue, cyan blue, clean and distinct color layers, strong tech atmosphere. Lighting: Overall dark background glowing effect, cloud outline, city building lines, ground road lines all have self-luminous neon glow effect, soft halo diffuses at element edges, bottom ground has clear reflection shadows of buildings and light sources, light is transparent with tech layering. Composition: Vertical symmetric composition, glowing cloud icon placed at the visual center of the upper part of the画面, digital city buildings arranged in the lower middle part of the画面, bottom digital road extends and converges from the bottom of the画面 towards the buildings, showing strong sense of depth, clear upper and lower structures, highlighting the core subject status of cloud computing. Usage: Commercial tech illustration that can be used as promotional posters, PPT backgrounds, official website banners, event main visuals for tech fields related to cloud computing, big data, smart cities.
