The way I view both photos is that you are documenting a beautiful work of art. In my opinion, this is best viewed straight on frontally. If you were shooting a painting or a sculpture, would you shoot it slightly from the side? Not unless there was a thematic or contextual reason which I don't see here. Also, your composition in the first photo oddly cuts off part of the frame around the relief.
Your dappled light on the second photo draws my eye to a small, bright point at 2 o'clock on the circle, and keeps my eye there. As an artwork, it's the relationship of the three concentric sets of circles that is the most meaningful, and that is better served by having uniform light. Just my 2 cents.
