Create a high-definition, fairy-like Pixar style image using Octane Render, depicting a young person sitting under a massive, lush tree filled with vibrant leaves and dappled sunlight. The character is surrounded by scattered books, symbolizing a journey of learning and reflection.

Use a 4:3 aspect ratio to emphasize the grandeur of the tree and the intimate setting
