So I've made some more progress on the Blast From The Past diorama. I had to make some layout changes to still fit the Delorean and the details on the side of the store. I was not getting the depth I needed to put in the US AIR poster and side door and this was an important detail. What I did was rip off the back I had originally made and put the entire structure on an angle. This way I get the depth I need on the left and road space to fit the Delorean.
