From the artist:

“A really nice piece for sirkain, featuring their character Kendall and my own Abby.

A lot has changed throughout the years for these characters and both have quite the history of reiterations, from both minor visual style tweaks to new or entirely different features, sometimes having a story of sorts tied to its inclusion. It's been fun to see these characters evolve over time, and I'm tickled to see what'll happen to them further down the road. =3”
