I have to admit, I laughed so hard I almost choked on a peanut when I saw the title of this post. I love that film. I'm curious, have you seen Isidro Ortiz's Eskalofrio? It's a deeply creepy, very atmospheric movie about feral children and vampires, along the same lines as Låt den Rätte Komma in. The production designer, Pilar Revuelta, worked on Pan's Labyrinth. If you haven't seen it, I cannot recommend it enough.
Oh! And before I forget/pussy out, here are those sketches. (Please keep in mind: I drew them when I was a Junior in high school, so they're... rough.)
