Create a highly realistic 3D abstract artwork featuring bold, metallic textures. The image focuses on floating geometric shapes—spheres, cubes, and pyramids—with soft reflections on a polished surface. The lighting is ambient with soft shadows to emphasize the depth and glossiness of the objects. Use a minimalistic background in a gradient of muted pastel colors, allowing the 3D shapes to pop out. The camera angle should be slightly low, using a 50mm lens with shallow depth of field (f/2.8), keeping the nearest object sharp while subtly blurring the rest. The central focus should be on the largest sphere, which is covered in a liquid gold texture, creating a sense of elegance and futuristic design.
