Adding spent shells & ammo boxes. Maybe add an MG team next to the AT Gun?
It's a start.
The gun is an older Italeri kit. The figures are from Miniart.

This is my other diorama of a German Pak 40 team in a building ruin. I scratch built the building. The Pak 40 is a Tamiya kit, the officer is a dragon figure from one of their figure kits.
I like the picture on the wall , lol.
It's not done yet , but close.

The next picture is a Russian 122mm Divisional gun by Trumpeter. The figures are a mix of Tamiya, Dragon & Miniart. The base is styrofoam , made like the first diorama . The wood planks are Popsicle sticks.
Not finished but close.
Hope you like them.
