I love these posters! It's somewhat ancient looking and it captures the feel of the scene well of how rubble is seen everywhere and the air looks polluted with dust from the demolished castle. Also the same type of sandy dirt rests on their clothing. It totally brings out the feeling of war. They don't look all polished and shiny as if posing to take fancy shots for a movie poster, rather you can almost smell the scent of blood and sweat coming from them by those exhausted and battle worn appearances. Also, Voldemort looks like a stone statue. Just thought to point that out.
