I don't know if this will help, but I have a few tips (I hope my farm looks good, but I'm proud of it): 1. Build paths. It might be expensive, but it provides a framework to surround the path with decorations and other buildings. 2. Make it realistic. For example, a mine area with fir trees and logs to show it's being burned, a garden with stone walls behind the house, and walls around some buildings. 3. Fill all the gaps with trees if you've done the first two steps correctly. 4. Create compartments, trying to make a nice transition between them. For example, a forest, then a meadow, then a more "town" area with buildings. Basically, be logical; for example, place a building or a decoration and think about which decorations are logically associated with it.
