Nice, but, remember: All terrain to be used with 1/72 actually needs to NOT be 1/72. It needs to be something like 1/78 or 1/82.
The reason is this: if you have buildings the same size as the figures, they are going to be occupying space that is WAY more than would actually BE the case for the actual building in space/time.
For instance, if one stand of 5-8 figures is one company, or in some cases one battalion, a 1/72 building is going to be WAY out of scale for space/time. The buildings and all terrain need to be something smaller than the actual figures; like about 15% smaller.
In other words, with 15mm troops, you can use 15mm buildings because the visual is already pretty small, but with anything larger than 15mm the visual discrepency becomes exponentially huge with each centimeter. This is a noticeable issue on the game table. Imagine in you will, a barn or windmill. Clearly, a 1/72 windmill would be GINORMOUSLY out of visual scale, even though it is in actual scale with the miniatures. A 15mm windmill would be too tiny, so it has to be something in between.
This is the entire problem with 28mm and why we have abanonded it in favor of going back to 1/72 everything, even 1/72 ships, because anything smaller than 1/250 size ships is a waste of time because you CANT SEE THEM on the game table.
This is a space / time conundrum we have solved by making all paper buildings just a wee bit smaller than the figures, something like 18-20mm instead of 1/72 which is 22-24 mm.
I know this ALL sounds like splitting hairs, but believe me, the difference is HUUUUUUGE when terrain matches figures. Or DOESNT, which is my point.
