Old sketch of two of the main characters from a horror novel I started but never finished. They are the Brothers Kirkpatrick, Exorcists for Hire. I was initially inspired to create them after watching Boondock Saints for the 50th time, but after Supernatural came out, the story kinda died.
I really need to do something with them, because they are pretty awesome.
btw, the one on the left is Gabriel and the one on the right is his older brother, Mikael. And yes, their names are intentional. Their father is a goof.
