I had fun making this. I think I'm going to turn this concept scene into an arcade game based on air defensive artillery batteries. But I need to I need to re-do it. I want to replace the Axis 88mm here with the DAZ MK1-40MM AA gun instead since its a USMC model. The figures will be Michael 3 with custom uniforms if I cant find proper vintage USMC garb. If you see any more flaws, I'm seeking critique for technique and historical accuracy.
