Smaug protecting Bilbo.
I love The Hobbit: An Unexpected Journey. I actually only decided to go see it because Martin Freeman was playing Bilbo and Benedict Cumberbatch would be playing Smaug. So when the end of the movie came and the credits rolled I was super pissed and actually said "This is bullshit!" out loud cuz I was so looking forward to Bilbo and Smaug together on screen. So yeah, I'm dying for The Desolation of Smaug.
I have been reading some Hobbit fanfiction, and a popular description for Smaug's human form is Sherlock because of Benedict Cumberbatch's role as Smaug's voice for the films. So here's some Smaug!Lock protecting Bilbo. From what? I have no idea, but Smaug isn't happy.
And I apologize for the smudges. I tried to draw this in pen but it just didn't work out.
