Some of my thoughts about the really not easy to do scene of fleeing soldiers.
At first,play with the scene.
Put things in positions you think alright.
And then start to change everything. Step by step. Till you have change each figure, car, house.
Do that several time. You get a feeling what is possible, you like, don`t like. The figure is useful or not.
Put your stuff in an angle. Avoid German Ordnung. So you get more room. Sound silly, just do it.
You do a action, running scene in front. And the rear is the calm with the wounded scene.
The Austin red cross is parked between the house ruin and the first aid post. Doors open to the street of fleeing soldiers. Or the doors open to the other side. The Austin split your wounded scene into two
one house, one first aid point scenes.
Use pose in move (only one feet touch the ground) on the retread road. More as standing pose. There is the action!
I think your officer who stop one with each hand is nice looking but very unreal.
Try to stop only one people who is running in panic. And he will stop two ?
One officer by the car with the pistol and the other officer by the car (without stopped soldiers) on the other side. Two non move pose in the action section is enough.
Open the door of the car.
Wish you the moment:
"Like this, that`s it !"
