The official site for the Harry Potter and the Order of the Phoenix movie has been updated to include a section on Death Eater masks. You can view current art from the movie as well as create your own and post it on the site for all to see.
To get started, download the 'Death Eater art kit' which contains some items you might find useful, or create your work entirely from scratch. Register to post your artwork on the site. Your art can be rated, downloaded, embedded on your blog or you can send it to a friend.
Thanks to Warner Bros. for the update. Go check it out.
