Some of the changes include: a working gatehouse to keep the baddies out, door locks on all the npc homes, an underground mushroom biome with a truffle (his name is cremini ) and a few other things. I tried to stay as true to the original design as possible without using paint 'cause that would be cheating, but other than some minor changes the castle is pretty much the same. After about two months of procrastination, one computer crash, a five week vacation, and about two weeks of actual work the castle has been finally renovated to look as cool as it did when it was first made (before relogic changed the textures).
