A beautiful princess sitting gracefully beneath towering ancient trees, reading a book in her lap. Sunlight filters through the dense forest canopy, casting soft golden rays on her flowing gown. In the distant background, a majestic and grand stone castle rises above the treetops, partially veiled by morning mist. The scene is tranquil, magical, and fairy tale-like, with rich natural colors, detailed textures, and a cinematic depth of field. High fantasy, ultra-detailed, 4K, storybook illustration.
