If I'm going to keep making TARDIS-themed customs, I need to come up with some more creative names than TARDIS, TARDIS 2, etc. ;)
Timey-Wimey was a commission for a TARDIS-themed pony with a pink body. After some further discussion, we agreed that she would have a TARDIS symbol, with blue hair. I also decided to do her eyes entirely in shades of blue, as well.
She started out as a Pinkie Pie (obviously). Her hair is nylon Forget Me Not blue. Her eyes and symbol have been hand painted in acrylic and sealed.
I have it on good authority that her new owner was very happy to receive her.
