Create a Matisse-inspired autumn design, featuring bold, abstract shapes and vibrant colors. The design should use a palette of deep autumn hues like burnt orange, mustard yellow, and rich burgundy, paired with rose pink and touches of shimmering gold. Incorporate organic, flowing leaf shapes, arranged in a playful and harmonious composition, typical of Matisse's cut-out style. The overall look should be modern yet timeless, with a balance of warm autumn tones and the soft elegance of pink and gold, creating an artistic and aesthetically pleasing design that feels both nostalgic and fresh. --ar 2:3
