I really like the way this turned out - I especially love your ground texture. Something to think about if you need thin yet strong wood beams- use bamboo skewers. They come in a variety of sizes and are very strong. I understand that you were using pre-bought pieces on the wagon, but if you were to make one from scratch, the cooking fire would be in a metal brazier, stone does not travel well. Overall this does look great and I love the added story details this would add to a city layout.
