I have no idea if this has been done before, but if it hasn't it could be useful.
Do you know how the gravestones sit on top of the fern that sticks out in the graveyard? Well I shortened the fern to stop the gravestones looking VERY wierd. Here is a pic of the graveyard with and without the mod. By the way, if there are any artistic people out there, they might like to copy my mod, but make it a little more realistic.
Attatched are the two image files that you can add to your Virtual Villagers - If you want to.

Hope you like it, and remember if you think you can do a better job than me, PLEASE DO IT!!!
