Create a black-and-white line art image for coloring, designed for anti-stress coloring books. The image should feature a powerful wolf as the central figure, with its fur and body intricately adorned with detailed mandala patterns. The wolf should be depicted in a proud, standing pose, with the mandala seamlessly integrated into its form, flowing through its fur and tail. Surround the wolf with additional mandala elements, such as geometric and organic patterns, that enhance the overall composition. Ensure the lines are clean and smooth, with a rich variety of fine details to provide a relaxing and immersive coloring experience.
