Transform Anger into Empowerment | Mastering Anger

Design a modern and impactful cover for an e-book titled "Mastering Anger: Practical Strategies to Transform Emotions and Improve Relationships". The cover should evoke a sense of calm and emotional control, using soft colors like blue and green to convey serenity, balance, and transformation. Include a visual element representing anger or tension, such as a stylized storm or flames, gradually being calmed or controlled by a human figure or a symbol of balance (e.g., a circle, scales, or a smooth path). The title should be prominently displayed in a bold, professional font, with the subtitle in a smaller but clear size. The overall design should be clean, inviting, and convey a sense of hope and tranquility without overwhelming the viewer.
