Act as a cyberpunk graffiti artist with a decade of experience in covert urban art. Create a detailed image of a massive corporate headquarters in a neon-lit dystopian cityscape, with your signature graffiti tag prominently displayed. The tag should incorporate [futuristic neon lettering] that glows in vibrant electric blue and pink hues, blending seamlessly with the building’s sleek black and chrome exterior. Surround the tag with [abstract cybernetic patterns] resembling circuitry and holographic glitches, creating a sense of rebellion against the corporate overlords. The scene should include [subtle dystopian details] like flickering LED billboards advertising oppressive products, drones patrolling the area, and rain-soaked streets reflecting the neon chaos. The overall mood should be edgy, rebellious, and visually striking.
