card buildings

i was looking at old buildings and liked the crumbling old stone, so i tried 2 re-create that effect with demin and felt but didnt work to well. i also made a treasure/pirate map of the kings island area, then decided i'd make a 3D map. so i made some of the buildings that were on the map from card. now i'm thinking of making a little village type scene with the little buildings but have it all seen through a window, like as if ur inside one of the houses looking out at the others. the card buildings are white but i think i'll put in black detail on them and have the outside world dull like old black and white photos. the inside of the window the veiwer is looking out will have bright warm colours. thats it so far!
