A weathered lighthouse standing sentinel on rugged granite cliffs at golden hour, traditional watercolor painting, loose wet-on-wet washes depicting white tower with red roof silhouetted against dramatic sunset sky, warm amber and pale gold light from setting sun casting luminous glow on stone and creating long shadows across windswept grass, cool steel blue and deep indigo tones of crashing ocean waves below and distant horizon, visible delicate brushstrokes capturing sea spray and scattered seabirds in flight, paper texture visible throughout, solitary serene mood, centered composition with lighthouse as steadfast focal point amid endless rolling sea and blazing evening sky
