사이버펑크 생체기계 뇌 그래피티 벽화

A wide photorealistic nighttime urban graffiti mural painted on a concrete wall in a gritty alley, viewed in realistic perspective. The mural fills nearly the entire frame, centered on a massive cyberpunk biomechanical brain—half organic with segmented pink and purple brain folds, and half machine with metal panels, cables, circuit boards, protruding rods, wires, and antennas. Painted across the brain is a large 3D graffiti lettering tag reading "[GeniArt]" with [orange]-to-peach highlights, dark purple shadows, black outlines, sharp angular spikes, and a bold street-art aesthetic. In the background, sci-fi neon [orange] laser streaks, [purple] electric tendrils, glowing magenta energy nodes, circuit diagrams, interface panels, and technical HUD graphics explode across a black and deep violet wall. Exactly 5 glowing [purple] energy orbs surround the mural—upper left, upper right, lower left, lower center-left, and lower right—each casting branching violet light trails. The color palette focuses on [orange], [purple], black, charcoal gray, metallic silver, and deep violet. Crisp spray-paint textures, realistic concrete grain, subtle paint drips, cinematic neon glow, with adjacent alley walls covered in small tags, wet asphalt sidewalk at the bottom, and distant ambient urban lighting. No people, no vehicles, no watermarks, no extra readable text.
