On the left is Pink Pearl, the future owner and manager of Sweet Apple Acres and on the right is Tally Mark, the mayor of Ponyville. It wasn't stated in the chapter itself but I get the impression that the two of them are best friends and had all kinds of crazy adventures before they had to be responsible adults. Well, more like Pink Pearl lead the way into the crazy adventures and Tally Mark felt obligated to follow and clean up after her and/or make sure she didn't get herself killed or anything.
As a note, this was drawn with a pall point pen then colored digitally. In case anyone was curious.
