The wall crack are too bold and too neat. The ruined buildings are also still too clean. The ruins should be more scattered along the width of the street, since it seems to be concentrated along the edge of street where the building stands for. In the other side, I really love the idea and lots of broken windows. Great tanks (should be more dirt and dust on it), nice figures' face expression and positioning. Very good job overall!
One more thing, I think Miniart may get frustrated since you broke their 'Apotheke' house in half.
