TARDIS Exterior: The Postbox TARDIS
Why I went with this design: I came up with it because I walked past an open postbox today, and thought "wow, that'd make a great TARDIS exterior!" Royal Mail postboxes are cool. I tried my best to design it in blockbench, but I have never used it and frankly, it looks horrific, but I'm still gonna enter it haha
