I thought I should update this note to say:
Feel free to draw the rest of the shop buildings if you please. I am very busy right now and won't be able to come back to this for a little bit. Note again that the individual shop buildings/rooms that I've added already (the ones across from Woolworths such as the gift store, the butcher etc.) very likely still need adjustments to the size of the. I think they are pretty close to perfect though; it's hard to tell for certain from satellite imagery.
