Contacting John Howe

I just sent an email to John Howe, an incredible Tolkien illustrator, who drew the set of maps in The Maps of Middle Earth. I sent him the link to my blog and asked if he had any tips. As an avid fan, it feels like I just asked Adele for singing lessons. I know so much about him and his art from my obsessive watching of the special features and commentaries of the movies. I really hope he emails me back.
