this one is a much more defined in detail and shading.
but I thought it would be nice, if the doctor took Derpy to see the stars in space and while in that moment they share a moment together.
I am not very good with inner details of the tardis..because I wouldnt know how to design it let alone how to plan out everything. It was just a hassle with the Doorway.
