Craft a dramatic, large-format acrylic painting of a powerful ocean storm approaching a rugged coastline. Massive waves crash against rocky cliffs, sending spray high into the air. A lone fishing boat battles the turbulent waters in the middle distance, emphasizing the overwhelming force of nature. Dark, brooding storm clouds fill the sky, tinged with ominous grays and deep blues. A lighthouse on the cliff face bravely cuts through the gloom, its beam a solitary sign of defiance against the wild sea, illustrating both destructive power and enduring hope.
