Colossal Dragon Coiled on Stormy Lighthouse

Dark fantasy digital concept art of a colossal [red] dragon coiled tightly around a weathered medieval stone lighthouse atop a jagged sea cliff. The dragon features immense outstretched batlike wings spanning nearly the frame width, torn leathery membranes, black horned spines along its head and neck, sharp talons gripping ancient gray masonry, and a serpentine body spiraling up the tower. Its head curves downward beside the lantern gallery with a fierce predatory snarl, glowing eyes, ridged scales, and rain-slicked highlights. The ancient lighthouse has small arched windows, ruined battlements at its base, and a warm glowing beacon at the peak, partially encircled by the beast. Set during a violent [thunderstorm] at night, under a purple-black sky torn by branching backlit lightning, diagonal sheets of rain, and turbulent storm clouds. Below, massive navy ocean waves crash violently against sea cliffs, churning white foam. Epic scale, cinematic dramatic perspective, painterly fantasy realism, moody violet and crimson palette, wet reflective surfaces, volumetric atmosphere.
