Thanks for all the positive encouragement.
Wow!
Just wow!
This is super impressive, the number of layers/levels and the completeness of the terrain. What materials is it constructed from?
Lots of 3D printing in both filament and resin, some balsa wood and card.
Fantastic! 
Thanks, It was your VSF buildings from years ago that got me started on this crazyness.
We were impressed when trying to suggest 'faces in the windows.'
Consider me ratcheted up to gobsmacked!

Thanks, I have the birds to add and still need to do washing lines and print out some cats as per your previous suggestion, but they are on the to-do list
