Kling Image v3

{
  "model_id": "fal-ai/kling-image/v3/text-to-image",
  "prompt": "An exhausted lighthouse keeper standing alone inside a giant storm-battered lighthouse during a violent night thunderstorm. Heavy rain crashes against massive circular windows while ocean waves explode against the rocks far below. The keeper wears a thick weathered wool coat and holds an old lantern that casts warm golden light across the dark room. Maps, nautical instruments, journals, ropes, and wet wooden furniture fill the lighthouse interior. Lightning flashes briefly illuminate the rotating lighthouse mechanism above. Foreground: blurred rain droplets on the window and warm lantern reflections close to the lens. Midground: the lighthouse keeper sharply focused with realistic skin texture, wet hair, tired eyes, and detailed clothing. Background: stormy ocean, crashing waves, rotating lighthouse machinery, and distant lightning fading into atmospheric darkness. Ultra cinematic realism, emotional storytelling, warm vs cold lighting contrast, volumetric rain and fog, rich environmental detail."
