Dragon Coiled Around Lighthouse in Storm

Dramatic high-fantasy concept art of an enormous, serpentine [red] dragon coiled tightly in an S-curve around a weathered medieval stone lighthouse on a jagged sea cliff. The dragon features glossy scales, sharp horns, spinal ridges, glowing eyes, an open roaring maw, and sharp claws gripping cracked gray masonry, with one vast torn membrane wing spread across the right frame. The old lighthouse has arched windows glowing with warm amber light and a glowing lantern room at its peak. Setting is a violent night [thunderstorm] with diagonal sheets of rain, purple-black storm clouds, bright branching lightning bolts silhouetting the wing, and crashing ocean waves exploding in white sea spray below. Low-angle cinematic shot, centered lighthouse, sharp textures on wet stone and reflective scales, intense contrast between cold blue-purple storm lightning and warm lantern glow.
