Yessss, some awesome reference pics! This is completely the wrong war, but I love the juxtaposition of the quaint French town with the tension of the French soldiers occupying it. It's a much cheerier scene than what I'd like to have, but I figure it's a good starting point. Now I just need to make the weather cold and gray and make the townsfolk miserable and I think we've got an environment brewing away!
