Ancient sea monster rising from a stormy black ocean

An ancient, colossal kraken, with eyes like burning embers and skin textured like weathered obsidian, breaches the surface of a tempestuous, ink-black sea. The backdrop is a ruined gothic castle perched precariously on jagged cliffs, half-consumed by stormy waves and mist. Sky is a turbulent canvas of deep reds and greys. The art style is a hyperdetailed, epic fantasy illustration with surrealist undertones, inspired by the grandeur of Frank Frazetta and the dark imagination of Wayne Barlowe, bathed in dramatic, cinematic lighting.
