Design a large world tree with a natural and simple style. The tree should have a massive trunk, wide roots spreading across the ground, and a large canopy. Use clean, simple materials and avoid excessive decoration. Keep the shape organic and slightly irregular, not perfectly symmetrical. Add a few branches and layers, but keep the overall design readable and not overly complex. Focus on strong silhouette, natural form, and balanced proportions. Avoid unnecessary details and keep the design clean and minimal.
