Generate a 32x32 pixel tileset suitable for a 2D pixel art game. The tileset should include a variety of terrain and environmental elements, such as grass, dirt, water, rocks, trees, and buildings. Each tile should be distinct and visually appealing. Ensure that the tiles seamlessly connect with each other to allow for smooth level design. The art style should be pixelated and have a retro feel, with a limited color palette of 16 colors. Additionally, provide a preview of how the tileset would look when arranged in a 4x4 grid to demonstrate its tiling capabilities. | Anything
