Cyberpunk Brain Graffiti Mural

Create a wide photorealistic nighttime urban graffiti mural on a concrete wall in an alley. The mural should fill almost the entire frame and show a huge cyberpunk biomechanical brain at the center, half organic and half machine, with segmented pink and purple brain folds, metal panels, cables, circuit boards, rods, wires, and antenna-like components protruding outward. Across the brain, paint a large sharp 3D graffiti word in stylized lettering reading graffiti_word, with orange-to-peach highlights, dark purple shadowing, black outlines, angular spikes, and a dramatic street-art tag aesthetic. Behind it, create an explosive sci-fi composition of neon orange laser streaks, purple electric tendrils, glowing magenta energy nodes, circuit-diagram patterns, interface panels, data blocks, and technical HUD details on a dark black and violet background. Include exactly 5 bright purple glowing energy orbs around the mural: one upper left, one upper right, one lower left, one lower center-left, and one lower right, each sending branching violet light trails outward. The color palette should emphasize primary_neon_color, secondary_neon_color, black, charcoal gray, metallic silver, and deep violet. The setting is a real gritty alley with adjacent walls covered in smaller graffiti, a concrete sidewalk and street visible at the bottom, subtle urban lights at the sides, and realistic perspective showing the mural painted on a flat wall. Use high contrast, crisp spray-paint textures, realistic concrete grain, paint drips, glowing highlights, cinematic lighting, ultra-detailed linework, and a symmetrical centered composition. Avoid people, vehicles, logos, watermarks, or extra readable words beyond the main graffiti word.
