One thing I forgot to mention in the descriptor captions on the pics, was to add that all the white paper window sill boxes inside the windows, will be recovered with wood grain paper strips glued over top of those white sills, so it looks more like wood window casing..more correct and better finish, and the wood grain complimentary of the other colors.
The real trick is that, all those shadow box sills were put in place before final assembly, and as you can see, there are alot of upstairs windows, and that hole in the ceiling of the first floor, does not allow my hand, so all the wood grain paper sill strips will have to be dry fit and bit cut and finesssed into place through the window openings.
A whole lot of ship in a bottle type of stuff...but borrowing from Rhaven's signature..."If it can be thought of, it CAN be done"
