Awesome and deeply artistic and powerful. I Love how you resisted the urge to put a vehicle in it and to focus on the human aspect of war; the loss, the loneliness, the quiet trgaedies that never make it onto the Hollywood screen. WELL DONE, and impressive in the skill of building!
As a side note, I did a vignette very similar to this with the same general figure layout and called it "Fur Die Vaterland" Nowhere near as impressive in scale, and using Revell figures in the same poses. :)
