A traditional lighthouse perched dramatically on rugged coastal cliffs during a stormy sunset, traditional watercolor painting, loose wet-on-wet washes depicting weathered stone tower standing resolute against crashing waves, cool steel blue and soft violet tones of dramatic stormy sky, warm amber and soft coral light from setting sun breaking through dark clouds catching lighthouse windows and creating luminous glow on wet stone, visible delicate brushstrokes capturing rough cliff textures and splashing white foam, paper texture visible throughout, dramatic contemplative mood, diagonal composition with lighthouse as stoic focal point amid endless turbulent ocean and distant rain-shrouded horizon
