For my 2015 Free Comic Book Day story "Service to Seyan" (included in the short story collection Baldwin the Brave and Other Tales), I built a model of the gatehouse that leads to the mouse version of the Elysian fields.
I made a video where I talk about this model, how I built it, what the materials were, and why I built it in the first place. Below you can watch as I explain how having the model helped frame scenes and block where the mice should stand in them:
