I couldn't help but compare this relief to the replica in the Manti Tabernacle:
While the image itself is almost exactly the same (except for some changes to the buildings, hills, etc.), the colors are very different. In Manti, they're muted; here, they're quite vibrant, but still done in soft tones. I really like the effect.
Finally, in going throughout the building, there is woodwork all along the walls, even in smaller hallways. It really gives the chapel a nice feel.
