It's all laid out exactly how I want a museum to be. Enough room around each piece of glass to be able to see it properly and study it, no fussy backgrounds, and well-lit.
I am wondering about the security and strength of the glass walls and doors on your cabinets; if you get folk like me visiting, I have a tendency to bang my forehead off the glass, while trying to see around and under things.
I'm not worried about my forehead, but causing damage to either the cabinet or its contents.
When I'm all focused on the contents, I forget there is a hard wall in the way.
