I love the diorama!
My favourite arrangement is the photo you posted in March.
I'm thinking that because the shelf is narrow, it will tend to look "crowded" with the diorama and other large and/or framed icons sitting on it. Can the diorama be hung on the wall? Maybe if the dorama was mounted on the wall as a centrepiece, with other large and framed icons arranged around it, with the smaller icons and statuary on the table, it would look less crowded and no less pleasing
Yeah, the March arrangement is a good one...
Unfortunately I don't trust the wire hanger on the back to actually hold the diorama, which is why my Godfather had custom-made the shelf for me (if you notice in the older pictures there's a little raised spot right in front of the diorama that keeps it in place). I think I might need to get non-print icons that don't require such large frames... maybe that'll balance out the look a bit better.
I actually rearranged the room, so my icon corner is facing east for the first time in a year!
Here's the new transitional look:
