This is my castle with four towers and four walls. The walls and towers are copies of each other. This didn't have really any pre-planing, but while i was making it i decided that it needed to have a flag and a landscape. I stared with making the towers and then the walls. The towers were made using two cylinder and using difference to shape the tower. I don't think i would do any thing different if i had to do it aging. It's is perfect the way it is. The only real problem i had with this was with the bump mapping looking really wried sometimes.
