I promised I'd post pictures of my display today, so here they are!
I'm 90% happy with how this looks now, and I know exactly how to tweak it for my next miniature show in June. I'll be adding some risers and steps to display my food and doing away with the wood blocks in front.
The room boxes are (from left to right): a chocolate/candy shop, a grocery store, a retro diner, and a bakery. I still need to add in some signs and decorations, but the boxes have their wallpaper and floors and set pieces of furniture (minus the diner that still needs a few more stools).
