I want you to design a wall of 250 x 300 meters for the entrance of a modern restaurant that does not use a lot of stone. The design of the sculpture is inside the wall, with abstract and three-dimensional faces with geometric shapes and lines, similar to the concrete sculpture shown in the picture. Each face should have a unique set of features, but maintain the same stylistic approach, emphasizing contours and raised surfaces to create a sense of depth and texture. Backgrounds should be minimalist, with neutral colors to enhance the visual impact of the sculptures. Create a collection of images including abstract and 3D figures with geometric shapes and lines, similar to the concrete relief sculpture in the image provided. Each face should have a unique set of features, but maintain the same stylistic approach, emphasizing contours and raised surfaces to create a sense of depth and texture. Backgrounds should be minimalist, with neutral colors to enhance the visual impact of the sculptures. Modify the previously created image to accommodate the user's requested changes, while maintaining the style of abstract and geometric wall art with a minimalist aesthetic. Make sure the stylized human face has a unique facial expression or feature and include subtle variations in background elements.
