Thank you Joe!
I have done some modifications to my modifications lol
1st floor was flimsy due to the thin styrene sheet I used so I strengthened with some 1” x 1/4” strips laminated with the panel design to pose as a pony wall around the perimeter
I also painted the interior walls the same colour as the first floor module
I decided to make it easy to pull the floors out to detail for sanity sake
Here are some pics
