"When I was rereading the Harry Potter books a few years ago, I realized how much my perception of the characters had changed because of their movie portrayals," Katie told BuzzFeed. "So now I scour through the books and pick out scenes that are great, emotional character moments and draw them as accurately from the text as I can!"
Katie also diversifies the Harry Potter universe in her comics — and J.K. Rowling herself gave her stamp of approval!
I worked out a sort of alternate cultural family tree where characters are a lot more diverse than the expected mostly-white cast," Katie said. "A few months after I started drawing them like that, the casting for The Cursed Child came out and Noma Dumezweni was playing Hermione. J.K. Rowling pinned a tweet about loving black Hermione, with my art in it, so it was really exhilarating getting the author's stamp of approval on my art.
