In the spirit of the last movie coming out this week, I felt like drawing something Harry Potter related. This is from the scene in the third book when Harry conjures the stag patronus to defend Sirius against a swarm of dementors.
I used to draw from these books all the time when I was in high school. It's easy when J.K. Rowling's writing makes it such that there's an engaging image to be found on every page. The Prisoner of Azkaban remains my favorite book in the series.
