Kristen Perry - Artist
A new import from Ohio, Kristen is the latest cog in the "hushhush" Team Fortress 2 machine. Trained as a traditional artist with a visual communications design degree with an illustration concentration, she brings a commercial and advertising perspective to an otherwise sci-fi/fantasy appetite. As a digital artist, she holds Photoshop most dear, save the occasional lure of dark chocolate and black tea. You can find out more about Kristen and her work at her website: www.merekatcreations.com.
