Commission by *palestorm. This drawing is of a young adult Sweetie Bell as part of my fanfic story.
Originally I just needed a reference sketch of how she might look as an adult as old as Twilight Sparkle is, but I wanted to give it some context if I was going to have it commissioned anyway. In this instance, Rarity is invited to a upscale ball and doesn't know that her sister is going to be the spotlight singer, and she's singing Taylor Swift's "The Best Day". It is meant to be Sweetie Bell's tribute to the best sister ever, and Rarity can't help but try (and fail) to hide her tears from the adoring attention of her little sister.
