Snake in the Castle: Medieval Concept Art

A hyper-detailed concept art scene of a colossal snake coiled along a ruined arch inside a medieval castle. The serpent's iridescent scales glow emerald and gold as torchlight flickers along damp stone walls. Surrounding environment includes moss-covered blocks, heavy timber doors, iron chandeliers, heraldic banners, suits of armor, and gargoyle statues looking down. Composition emphasizes textures: rough stone, weathered metal, and reflective scales. Lighting is cinematic with chiaroscuro: warm amber torches contrast cool stone shadows. Camera angle is slightly low, focusing on the snake's eyes and coiled body, depth-of-field blurring the distant corridor. Mood: ancient, mystical, slightly ominous. Style: fantasy concept art suitable for a video game or film, painterly, high detail, 8k ready.
