宇宙星雲中漂浮島上的古老城堡

An ancient, crumbling castle perched precariously on a colossal, floating island, adrift in a nebula of swirling cosmic dust and starlight. Jagged, crystalline formations erupt from the island's surface, hinting at an alien geology. The castle's architecture is a blend of gothic grandeur and something far older, its empty windows like eyes staring into the void. Dramatic lighting emphasizes the stark contrasts between light and shadow, casting long, ethereal beams across the scene. Rendered in a cinematic, epic watercolor style.
