Kraken in the Subway: A Dark Concept Art Scene

Ultra-detailed concept art of a colossal kraken in a subway tunnel at night. Damp concrete, graffiti, and rusted rails; neon signage reflecting on wet surfaces. Bioluminescent blue-green tentacles wrap around tunnel arches, suction cups gleaming, one tentacle gripping a support pillar. A distant, foggy train tunnel rumbles with steam, casting moody backlit silhouettes. Dramatic, cinematic lighting with high contrast, cool teal and blue palette with rusty orange accents. Low-angle, wide shot to emphasize scale and menace; painterly digital textures, film grain, and atmospheric haze. Design-forward creature anatomy with armored, barbed tentacle tips and intricate suckers; feel like concept art for a film or game.
