So i decided to lay all the pieces out together to see what it looks like, and here it is:
The white one will become a trench system to join to the next one
View from the current trench, more balsa wood to add.
Ruined industrial complex.
I think i will add some brown on the join between the industry section and the open space ones, to make it flow better.
My updated radar tower. The edges of this board will be brown to match the trench system
The base of this board will be brown too.
Any comments are more than welcome as always.
