**Poster Design Breakdown with Modifications:**

1. **Title Change:**
   - Use "HERO OF LIGHT" in a bold, bright typeface.

2. **Background:**
   - Alter the background to a serene landscape at dawn with golden rays breaking through clouds.

3. **Central Figure:**
   - Feature a character dressed in simple, flowing robes, but with vibrant colors like deep blue and white, facing slightly sideways instead of directly at the viewer.

4. **Supporting Imagery:**
   - Include a group of diverse people in the background, depicting various expressions of hope and support, instead of the original scene.

5. **Lighting and Effects:**
   - Add a soft halo effect around the central figure to emphasize their importance, shifting from a sepia tone to a brighter color palette.

6. **Bottom Section:**
   - Remove brand references and credits; instead, include a tagline like “A Journey of Sacrifice and Redemption” in a subtle, elegant font.

7. **Overall Composition:**
   - Maintain a vertical layout but ensure there’s more negative space around the title for improved readability.

8. **Font Style:**
   - Use a slightly whimsical, handwritten style for the title to give it a more personal touch.

9. **Date and Release:**
   - Replace the release date with "COMING SOON" in a simple sans-serif font.

These changes retain the essence of the original design while introducing fresh visual elements.
