Since the basic shape had been done, i have been work on the details and materials to make this building looks more real.
As a big part of this building, the walls are very important, so i started with them. i did some researches about new walls and old walls which are very dirty and with cracks.

Because Sunyang shop is a very big and famous shop in that city at that time, then it could not be very dirty, but i don't want to make it too clean neither, because sometimes a little bit dirty could make object more interesting and realistic.
I very like the model in the picture below, because the details of the textures are not make people feel boring. Opponent, they make this building looks like has very rich details even the model is simple, also the textures of the ground and the walls can make people feel 'weight'.
i took the picture above as my main reference of the walls. i studied it and find the main colour is still white but not too white and the dirty parts normally at the bottom and a little bit at the top, that is because bottom parts are close to the ground and some people like to kick the wall with their shoes and the reason of top parts easy get dirty is the effect of water to the wall.
The important priority order of the walls is the bottoms, the tops an then the middles, because the bottoms are the most dirty parts and they show more details and then the tops, the middle parts are the cleanest parts compare to the other parts. Based on the important priority order, when i did this texture, firstly i gave the walls a base colour - white, the i add some dirty marks to the bottom parts, then add less dirty marks to the top parts, finally, add very less dirty marks to the middle parts.
