I wanted to make a scene for my alien/space defender minifigs from the LEGO® minifigure series. I tried a 8x8 square but it was too small. Instead I used a 16x16 square. The vig is of two space defenders(Galaxy Patrol and Intergalactic Girl) defend ruins of a alien base from two alien invaders(Classic Alien and Space Alien). Take a look.
The last two pictures showcase the "weathered" parts of the wall.
