That's pretty darn nice! The wagon tracks are a real nice touch, but you may want to put in a round about with the tracks in the front yard or around the back of the house as I doubt the horses are able to go in reverse that well with the wagon attached.
I assume thats a small cliff behind the house? Very nicely done, though I can't tell which direction it goes. Looks like you fall down into if from the house level.
Very cool, though I don't know we need to actually SEE inside the outhouse... heh.....
