"Create a modern isometric 3D illustration featuring a futuristic marketplace where art pieces, rare collectibles, and sculptures are being exchanged and displayed. Include digital interfaces and floating upward-trending graphs, along with 3D isometric objects like art and collectibles. The background should feature a sleek, geometric city skyline with clean, angular buildings, shaded in soft pastel tones of light blues, warm golds, and muted pinks. The overall scene should evoke a sense of modern technology, growth, and opportunity without including any layout or text elements."
