TARDIS Exterior: The Eiffel Tower TARDIS
Why I went with this design: tbh the thought just popped into my head and I decided to go with it. I also think the general idea of a small eiffel tower sounds fun. perhaps you could enter through the archway thingys at the bottom.

Feel free to write whatever else you feel necessary! I have to admit the model that I attempted doesn't look very great however I was under a bit of time pressure and did this in a rush so I decided to add that other picture :)

TARDIS Exterior: The toilet tardis
Why I went with this design: I just thought that I would be rather amusing having a toilet tardis in the mod

Feel free to write whatever else you feel necessary! This is a reentry of my first entry. Again the model isn't that great but I hope you like it anyway :). Also I just realized that the toilet seat texture rather looks like gray cheese . And as to where one enters the tardis I will leave that up to you to figure out ;)
