Nice look! Squalor is good. If the bones 'age' a little more and gross stuff appears on the wall (the kind that you don't want to touch) the better it will be. On the bricks, try adding a multi layer channel with a moss type of look and blend to the bricks with either the Snow feature or Digital Carvers Guild Altitude feature. That way you can have gunk growing and getting thicker as the shape changes. Just my thoughts though!:) Mark
