Create a digital painting inspired by the image of a young man standing in a train, illuminated by warm autumn sunlight filtering through the windows. Utilize a watercolor technique to capture the soft, golden hues of the environment and the rich textures of his coat and backpack. Incorporate a color palette featuring warm browns, deep greens, and vibrant autumn oranges to evoke a cozy, nostalgic feel. Employ sketch drawing elements to emphasize the contours of his face and clothing, blending realism with artistic flair. Ensure the composition reflects the tranquil beauty of urban life amidst changing seasons, creating a captivating moment in time.
