Design a cozy autumn scene featuring a textured orange backdrop that captures the essence of the fall season. The background should be a warm, inviting orange, reminiscent of autumn sunsets. In the foreground, create a dynamic arrangement of swirling leaves in a variety of autumn colors—deep reds, bright yellows, and earthy browns—creating a sense of movement and life. The scene should be illuminated by soft, diffused light that enhances the warm colors and creates a gentle glow around the leaves. This composition should evoke a feeling of seasonal coziness, making it ideal for a fall-themed art piece or a festive gathering. Consider incorporating subtle textures in the background to add depth and richness to the overall scene.
