The walls still hold, sort of

Some progress being made on the fortress I mentioned in the latest posts. This above is the first attempt, just threw together lego pieces of equal length. There is an artillery battery included to show the scale to the Risk units I own.

Now this is much better, I remembered I had some of these huge A1 papers so drew a pentagonal shape (marked a point, drew a line then 72° differences between four other lines starting at the same point), the sides equal the length of the longer lego pieces. 

There is a barracks inside and the old piece of vine I collected last year. All I need is some elevations, some of those thick cardboard pieces will do, or maybe foamboard.
