"A modern autumn-themed wall art design for a restaurant. The artwork should be displayed directly on a gray concrete wall, using a minimalist, contemporary style. Focus on still life compositions that include subtle seasonal elements such as pumpkins, autumn leaves, and harvest fruits, stylized with clean lines and abstract shapes. Utilize a muted color palette--burnt orange, deep burgundy, and muted gold--combined with neutral tones to create a refined yet cozy atmosphere. Integrate metallic accents like matte gold or brushed bronze to add a sophisticated touch. The design should feel modern and balanced, using dynamic layouts that play with depth and perspective. Incorporate geometric patterns and soft gradients to contrast with the organic shapes of the pumpkins and leaves. The overall look should be an elegant blend of seasonal warmth and artistic modernity, creating a striking visual focal point on the concrete surface."
