Tom Felton, best known for his role as Draco Malfoy in the Harry Potter movies.
EDIT: So! I met Tom at a convention in Belgium, and asked him to sign this drawing! Not only did he sign it, he also gave me a whole range of compliments and congratulations! He is one of the most amazing people I have ever had the privilege to meet. My friend filmed the whole conversation between Tom and me when I asked him to sign my drawing.. If you're interested in seeing it, you can find it right here on my tumblr: [link]
