奇幻沿海城市景观

A breathtaking high-fantasy coastal kingdom on a tropical island, with a grand stone castle rising on a lush hill above a bustling medieval harbor village, turquoise lagoon curving through the town, sandy beaches, palm trees, wooden boats and white-sailed ships scattered across a sparkling blue sea, distant green islands on the horizon, ultra-detailed panoramic composition from an elevated aerial viewpoint, bright midday sunlight, crisp blue sky with fluffy cumulus clouds, warm tan rooftops, sunlit stone walls, emerald foliage, shimmering transparent water, painterly storybook concept art with fine architectural detail, vibrant colors, cinematic scale, soft atmospheric depth, polished digital illustration, serene idyllic adventure atmosphere.
