Well.. wouldn't want to put you to too much trouble, but I'd need roughly the following:
32x32 (or characters which will fit within this grid space) little people (which can be simple recolours) with back/front/left/right views.
Some basic ground textures like grass, road, bush, tree, wooden floor for houses, etc (again, 32x32).
Signpost sprite (32x32)
Houses (which fill maybe 4 tiles wide and 3 vertically).
Some small pieces of furniture, maybe a chair, painting.
A couple of small 20x20 or so items (for the inventory), such as a key, health potion, sword, a few things like that.
