Smaug the fictional dragon from J. R. R. Tolkien's 1937 novel The Hobbit and appears in The Hobbit: The Desolation of Smaug.
I know, I know, another artwork of Smaug's eye like there isn't enough of it on the internet. I admit, I couldn't help it. I just felt the impulse to do my own drawing of it (cuz I love eyes and I don't mean that in a creepy way...they're just pretty). I use colored pencils and a black pen.
