Create a unique futuristic and highly detailed and realistic image of a large, modern shopping mall. The mall should feature an open gallery in the middle, allowing for a spacious and airy feel. Populate the scene with a diverse range of people, engaged in various activities such as shopping, walking, and socializing. The architectural style should be contemporary, with sleek lines, large glass windows, and sophisticated lighting. Include a variety of stores, cafes, and seating areas to enhance the vibrant atmosphere.
