Thanks for the compliment!
I am starting on a winter shelf diorama with a backdrop and I hope to have it done in the few weeks. It is pretty cold here right now so it is easier to relate to than summer scenes, although I wish that wasn't the case!
The first three winter dioramas we made were specifically for WWII, this one will be more universal so it can be used with other periods too.
If it stays as cold as it was last year, for as long as it did, I will be thinking about something tropical in about 90 days!
All the best!
