That's a constructive feedback ! Thank you Nige !
The hand car is a very good idea, I will certainly consider adding one (a scratsh) !
The reason for adding the brick rubble in the diorama is to give the scene more colour and variation. May be the house of the neighbours was made in another kind of material and was completely damaged ? This happened sometimes. A bigger diorama could have declared this, but I wanted to keep it compact for it is not that important I believe.
The German soldiers were not in the house (door is closed), but come running from the back yard (considering their poses they are under fire coming from that direction ?). Again, I did not want to create a complete back yard to declare this. But may be an opened door could have been nicer.
Your comment is very much appreciated and I will think about the similar looking poses of the two Germans. Again, thank you Nige.
