Ah, I see, I misconstrued which diameter and which thickness was which.

I also had the chance to open this up on a much bigger screen - and WOAH! It's really amazing. I love all your little details on the structure, the landscape, and the geometry. Putting in a view of the reflection of the other side of the ring really gets the viewer into the middle of it.
