It doesn't matter that the road signs are cardboard. They look the part for sure!
I love how you made the map, and made it look real!
I tried something similar with a Panzer III with Rommel and crew but the map that was supplied in the instruction was way out of scale...
But it really brings to the scene to include a proper printed map
The diorama as a whole is borderline perfect if you ask me. It's compact and minimalistic - and yet speaks volumes!
Really artful in fact. Well done!
