Great build of this diorama so far!
I also planned and built a scene, but for WWII, with wooden parts and glued elements for a previous campaign - "the Atlantik-wall".
But I must withdraw from this campaign because of personal reasons. (burn-out-syndrome, one reason is "no interest in all my hobbies" - all builds were stopped)
For my former diorama I used "styrofoam", (the "larger-bubbled" version of styrodur) but as I think, "styrodur" (the finer version) seems to be very better.
Also I cut, painted and glued wooden parts and placed them.
But I stopped working on my diorama.
My work can be seen in the "Atlantik-Wall-campaign".
To your Diorama: GREAT !!!
Very nice details of any parts, for me, very realistic looking earth and dirt-effects!
I also planned this looking appearance for my diorama!
thank you very much for sharing...
