Create a digital illustration of a young person standing in a bustling city street during autumn. The person is viewed from behind, showcasing a relaxed, contemplative posture. They have shoulder-length hair tied loosely at the back, highlighted with streaks of warm colors reflecting the autumn mood. They are wearing a casual, oversized orange hoodie that drapes comfortably over their frame, paired with dark pants. On their ears are large, cushioned headphones in a soft pink color, suggesting they are immersed in their own world of music. The city street is lively with the blur of pedestrians and the quaintness of shopfronts, with leaves in shades of amber and russet gently tumbling down the scene. The atmosphere is filled with a golden hue, as if the sun is setting, casting elongated shadows and a serene ambiance. The style of the illustration is a blend of realism and a dreamy, painterly aesthetic, with a focus on warm colors and a feeling of peaceful solitude in a busy environment --ar 16:9
