Lengthen the barrel.
can we only post models, or can we also post renders?
I don't quite understand the premise of your question. Do you mean like, scene renders? Because I'm pretty sure if you make it in a 3d modeling program, it's fine.
Try a StuH 42, it should be a pretty easy tank to stubbify
I would shrink the barrel a bit, you could fit someone inside.Otherwise looks nice.
Corpse-launching tank.Interesting.
true story during ww2 soviets would load artillery with the corpses of their fallen com4rdes and rain them down on the germans to display dominance
