Sounds like an interesting project, well timed, with the adverse weather and all, so fitting for the period.
Sadly, I can't view your last pic for some reason, but can see all the others. The work you've done thus far looks amazing!
I especially like the hoarding, and the roughened wall texturing, because both look very realistic.
Is the hoarding a printed paper detail you created?
What did you use to scribe the lines in the foam, for the blocks?
A mechanical pencil, like around the doorway, or something else?
Your work makes me want to try to do something similar, since I've got a bit of unused foam just sitting around.
Thanks for sharing your project, and photos.
