Detailed 3D Render Showcasing a Bird’s-eye View at a 45-degree

Create a detailed 3D render showcasing a bird’s-eye view at a 45-degree angle of an isometric miniature medieval village scene. The centerpiece should be a castle, surrounded by stone cottages with ornate timber-framed designs. Introduce a gentle snowfall, lightly covering the roofs and spires to interact with the environment. Apply physically based rendering (PBR) techniques with realistic lighting to emphasize materials like aged stone and weathered wood textures. Use a plain background that is clean and uncluttered, focusing on the model's precision and intricacy in the composition. At the top of the image, include the text "Medieval Village Snowfall -2°C" alongside a snowflake weather icon.
