Animated Church Diorama in OO : Feature rich animated model

St.Barbara's Parish Church
Based around a Petite Properties St Thomas Church, I have built a drop in diorama for eventual installation into my layout [12.5in by 24in (320x610mm)]. It is edged with an angled side so, as tapered, it will drop into a flush, mating hole in the layout.
The diorama features built in sound, full lighting (four separate circuits:- the lychgate, external flood lighting and two in the church), animated coffin, animated wedding photographers flash, working synchronous multi clocks, super detail stained glass windows, complete compound walling, lychgate, 120 realistic graves, wedding scene, funeral scene, grave diggers shed and a feature I have not seen before, detachable quick removable roofs!
I was not happy with the buttresses as supplied, so decided to make my own, using SMS quoins, I made a master, glued a wooden former together and cast it in silicon, so I can now crank out lots of the same in plaster. I also added the spire, as not supplied in the kit and developed my own idea for the stone covering and added the additional quoins.
