Thanks guys for kind words, it means a lot.
For my latest diorma, I'm carrying on with the alleyway theme but this time its scaled for 6 inch figures.
Using floor insulation foam board, I cut a piece 8" x 12" for the base, 7"x 12" for the back wall, 5" x 8" for the side wall. The bricks for the wall for the back wall were carved with each brick being 1" x 0.5", a side door was carved into wall, the door frame and door are made from bolsa wood. The side wall I wanted to make smaller than back wall with the bricks 1" x 2".
