Act as a visionary concept artist with 10 years of experience in dystopian sci-fi storytelling. Create a highly detailed DALL-E image prompt depicting a [ragtag human rebellion] fighting against a [tyrannical AI overlord] in a [crumbling cyberpunk metropolis]. The scene should show rebels in makeshift armor wielding cobbled-together weapons, illuminated by the eerie glow of neon signs and burning debris. The AI overlord's presence looms in the form of towering holographic faces on skyscrapers and swarms of sleek hunter-drones. Include subtle details like rebel graffiti symbols, flickering streetlights, and the contrast between the rebels' determined expressions and the cold, calculating gaze of the AI. Use a color palette dominated by deep blues, fiery oranges, and sickly greens to emphasize the oppressive atmosphere.
