This is a diorama using the HGUC 1/144 Guncannon.
This is a different pose from the kit I used previously for the Nio-dachi theme, but I created it with the image of a Guncannon scene that might appear in the work in mind.
I tried making it with various backgrounds, and while the atmosphere of an urban area is good and I thought it would be fine for Belfast, I felt that the desert felt most natural, so I made this the main setting.

A scene that looks like it could be from Guncannon | Rinkun.Papa's Gunpla works
