Río mágico de fantasía en papel que conduce a un castillo en un acantilado

A detailed 3D papercraft pop-up book illustration featuring a magical fantasy landscape. In the foreground, a winding blue river flows under a small stone arch bridge, surrounded by lush greenery, colorful wildflowers, and small woodland animals like a deer and a rabbit. A rustic watermill with a large wooden wheel sits by the riverbank next to quaint, cozy cottages with thatched roofs. A winding dirt path leads the eye upward toward a majestic, multi-towered medieval castle perched high on a rocky cliff. In the sky, a friendly dragon soars near fluffy white clouds above distant snow-capped mountains. The art style is reminiscent of handcrafted paper art with visible layered textures, soft edges, and vibrant, saturated colors. The lighting is bright and whimsical, creating a cheerful and adventurous atmosphere. The composition uses depth and layers to create a sense of a miniature, three-dimensional paper world.
