Aïcha Wijland is one seriously talented artist and can now boast that even J.K. Rowling (a.k.a. The Queen) chose her fan art as her favorite.
@jk_rowling posted a link of the fan art and wrote: "Today seems a very good day to share my favourite fan art of young Sirius with his best friend."
Wijland actually was not all that pleased with her creation, captioning it: "A seriously shitty sketch of the lads in front of their first flat," Wijland wrote beneath her picture. "Probably gonna regret uploading this but whatever, I'll make something better before the week is up."
She's probably changed her opinion since then.
