This task from "Use This If You Want To Take Great Photographs. A Photo Journal" was...
Make a portrait of someone without them being in the picture.
This shot is from Denise's office (AKA The Fortress of Dollitude) and is perfect as it captures her love of history and pop culture (see the TMNTs), a glimpse of her favorite piece of art (the Nike of Samothrace), and her greatest fear after zombies (the Titanic).
When I ventured in the Fortress I assumed I'd have to move things around a bit to get the shot I wanted. Amazingly, though, this was exactly how I found it.
