Here's a breakdown of the key differences between the two images:

*   **Lighting:** The synthetic image has much brighter, more uniform lighting compared to the original's dramatic shadows and diffused light.
*   **Color Palette:** The synthetic image features a significantly warmer, more golden color palette than the original’s beige, brown, and gold tones.
*   **Pews/Seating:** The synthetic image shows a full row of pews, while the original only displays a few in the foreground.
*   **Altar Detail:** The altar area in the synthetic image appears more detailed and elaborate.
*   **Perspective:** While both have converging lines, the synthetic image feels slightly wider and less compressed.



Overall, the synthetic image presents a cleaner, brighter, and more idealized version of the cathedral interior.
