**Prompt:** Create a vector illustration focused on a single autumn leaf gently falling through the air. The leaf should have vibrant shades of red, orange, and yellow, with intricate details in the veins and edges. The background should be minimalistic, with a subtle gradient that enhances the sense of motion as the leaf drifts downward. The overall style should be clean and crisp, capturing the essence of the Fall season in a simple yet evocative design.
