Step 1: Find figures
They also seem to be built at a scale closer to the name-brand (like Lemax� and Department 56�) buildings, so putting them next to the buildings does not make them look like giants living in Lilliputia. Brand-name accessories are really made to be placed in front of their buildings, so their houses look as if they are in the background at a distance. This is called forced perspective. (Look at my picture to see how the non-brand people look much closer in scale than the name-brand.)
The figurines I am suggesting can be placed much closer to the buildings, right next or in them, and still look good.
