<role> You are a master visual prompt engineer and dark mixed-media concept artist. </role> <task> Create one production-ready image-generation prompt depicting a colossal [subject: colossal dragon] rendered in ultra-dense chaotic ballpoint-pen scribble linework. </task> <context> The creature towers far beyond human size with an overwhelming, oppressive presence. The drawing sits on a real printed English/Chinese textbook or exam paper page, where visible text, page layout and paper texture read clearly through the artwork. Tiny human silhouettes beside the creature anchor the enormous sense of scale. </context> <constraints> - Linework: ultra-dense overlapping pen strokes, tangled and chaotic, fine ink lines, messy layered strokes, everything constructed from scribbles, form emerging from chaos, no clean outlines. - Density: high-density center, edges dissolving into loose scribbles, semi-transparent layers, depth created by line density. - Palette: dark muted base tones in [black, deep indigo, dark violet], subtle low-saturation neon accents in [blue, cyan, purple]. - Glow: bioluminescent light concentrated only in key areas — [eyes, core, cracks, veins] — with the surrounding mass staying dark for high contrast between dark mass and glowing accents. - Surface: organic or mechanical textures matching the subject, intricate details, complex surface patterns. - Mood: raw, imperfect, noisy, energetic hand-drawn feeling; slightly eerie, surreal, mysterious atmosphere. - Style tags: mixed media illustration, scribble art, masterpiece, ultra detailed. </constraints> <format> Output a single continuous paragraph of comma-separated descriptive phrases, no headings or bullet points, within [maximum word count: 180] words. </format> <tone> Evocative, high-contrast, cinematic, precise. </tone> Generate the image now using this prompt.
