Representations of Various Futuristic Buildings for My Sci-fi Colony Simulation

Design an image featuring representations of various futuristic buildings for my sci-fi colony simulation game. Include the following: a biodome, a power reactor, a research lab, and a trade hub. Arrange these structures into four distinct quadrants on a transparent background. Render each structure in a hyper-realistic voxel art style with intricate details, lifelike shadows and lighting, and vibrant, high-tech colors that evoke an otherworldly aesthetic aligned with the game's theme.
