Dragon-Coiled Lighthouse Storm

Create a dramatic high-fantasy concept art scene of a [dragon color] dragon coiled tightly around a weathered medieval stone lighthouse on a jagged sea cliff. The dragon is enormous, serpentine, and menacing, with glossy crimson scales, sharp horns and spines, glowing eyes, an open roaring mouth, clawed feet gripping the masonry, a long tail wrapped around the tower base, and one vast torn membrane wing spread across the right side of the composition. The lighthouse is old gray stone with cracks, arched windows glowing warm amber, a circular balcony, and a glass lantern room at the top. Place the scene during a violent [storm type] at night: diagonal sheets of heavy rain, purple-black storm clouds, bright branching lightning bolts behind the dragon and tower, and turbulent ocean waves exploding against the cliff below in white foam. Use a low-angle cinematic composition, the lighthouse centered, the dragon wrapping around it in an S-curve, the wing silhouetted against lightning, with intense contrast between cold blue-purple storm light and warm lantern glow. Render in highly detailed fantasy realism with dramatic lighting, sharp textures, wet stone, reflective scales, sea spray, motion in the rain, epic scale, and a dark atmospheric mood.
