This is actually some really nice and "original" idea (as some Mods may say).
This could be useful to many people, but I do believe that you should make it a bit more "dark" adding some web, or skulls on ground next to it, perhaps have another model where you have those type of Graveyards like how is in a "morgue" with shelves and skeletons inside.
I really like this, this is great for decorating "Catacombs", Well done once again.
