I’ll create a storm-lashed lighthouse scene with stark rock, sweeping rain, and a bright beam cutting through the darkened sky.

The composition places the lighthouse on a rugged outcrop at the right, with intense slanting rain, dark cloud masses, and a jagged lightning bolt in the distance. The warm beam extends strongly across the frame, while the restrained blue-gray palette keeps the mood turbulent and cohesive.
