That is just a fantastic piece of work. Wonderful job.
I also find it rather amusing that people are correcting you that Frankenstein was the doctor's name, not the monster...but then a couple of them go on to say the monster's name was Adam and that "everyone knows" this, when in fact, the monster never had a name whatsoever. Besides, what's wrong with calling the monster Frankenstein, really? Wouldn't a "son" take his "father"'s name? Plus, you say Frankenstein, everyone assumes you mean the monster, it's become vernacular.
Excellent! Love the modeling, and use of light and shadows on the head... you really get the feel of a solid bone structure underneath the skin. That's not an easy thing to do! Also, just a nice take on the classic monster.
