A solitary, weathered lighthouse stands on a rugged, windswept cliff overlooking a turbulent, dark grey sea. Jagged rocks are partially submerged by frothy, white waves crashing against them. The sky is overcast with dramatic, bruised-purple and charcoal clouds, hinting at an approaching storm. A faint, cool mist hangs in the air, obscuring the distant horizon. The overall mood is one of isolation, mystery, and impending drama. The color palette is dominated by deep blues, greys, and touches of muted, earthy browns for the cliffs. The composition is centered on the lighthouse, with the dramatic seascape filling the lower two-thirds of the frame. The style should be painterly, with visible brushstrokes, evoking classic gothic art or Romantic landscape paintings. Professional audiobook cover aesthetic, square 1024x1024 format.
