Awww. The Doctor took her on some lovely beach somewhere in this great multiverse of ours.
This is great! Hate to be nitpicky, though, but you forgot her cutie mark.
Me: "I would love to hang out for hours on end but someone has to take care of the minor not affecting time problems in the world."
Dr Whooves: "So you are going to hang out for a few minutes then?"
Me: "Of course as long as they do not end up equaling hours of course."
Derpy: "Of course not."
And then something washes up on the beach that lead to having to save the world (again).
Derpy and Doctor Whooves are finally getting some break time after travelling around the universe...
(BTW you need to get permission/clearance to sketch these, right?)
