So here is a lesson that was inspired by a member who suggested or requested or came up with an idea to fuse together Nightmare Before Christmas themed stuff with Doctor Who stuff. This fusion would make sense since both of the main characters travel between worlds. Jack uses trees and the Doctor uses a Tardis as a transportation device. So, having said all that, here is how to draw a Nightmare Before Christmas Tardis, step by step. I even placed the Tardis on the hill from the movie as a background piece but you can create your own idea.
