A great set of displays, Michael, and thank you for the link.
I like the children's summer camp. The Playmobil children seem to get overlooked in dioramas, so it's good to see one devoted to them especially with some great customs (e.g. the tents) and nice detail such as the table laid for the main meal of the day.
Then1900 diorama is quite stunning, especially the many custom vehicles and the lake in the park. Again, the detail points are wonderful, the poster being put up about the Luxplaymodays, the chess game.
I'll have a look at the rest later when I have more time.
