Illustrating Detailed Designs of Various Buildings for My Medieval-themed Real-time

Create an image illustrating detailed designs of various buildings for my medieval-themed real-time strategy game. Include the following structures: a monastery, a watermill, a fortress, and a trading post. Each building should be arranged in its own square on a transparent background. Render the structures using an ultra-realistic voxel art style, featuring intricate textures, dynamic lighting, vivid colors, and rich details that complement the game's medieval aesthetic.
