Malicious, psychotic, cunning, and a sick sense of humor: That's Smaug, all right.
They did him justice in the movie... and made him terrifying! From the second he woke up, to the second he declares death to Lake-town, Smaug was a monster with wings and fire. You did a good job in capturing that with this one.
"I am old and strong, strong, strong, Thief in the Shadows. My armor is like tenfold shields, my teeth are swords, my claws spears, the shock of my tail a thunderbolt, my wings a hurricane, and my breath death!" Love that part in the book (and movie). Smaug is my favorite part in the book and movies.
