Design a series of book covers arranged in a row, featuring the following changes: 1. **Color Scheme**: Use a gradient background with shades of green and yellow instead of blue and yellow. 2. **Book Titles**: - Change "YOUR OWN MONEY MAKING MACHINE" to "BUILDING YOUR PASSIVE INCOME". - Change "SEARCH ENGINE OPTIMIZATION TOOLS" to "MASTERING ONLINE VISIBILITY". - Change "THE WEIGHT WATCHER'S EFFECT" to "EFFECTIVE WELLNESS STRATEGIES". - Change "THE BRUCE LEE TRAINING SECRETS" to "UNLOCK YOUR INNER WARRIOR". 3. **Imagery**: - Use abstract icons or illustrations relevant to the titles (e.g., a piggy bank for passive income, a magnifying glass for online visibility). - Avoid any person or character images. 4. **Font Choices**: Use modern sans-serif fonts for a clean look. 5. **Layout**: Keep the books in a slight 3D perspective but ensure they all appear cohesive in width and height. Ensure there are no brand references or logos on any of the covers.
