I had only set out to draw Adam, but I already had a design in mind for Dracula... so why not.
Adam is an interesting challenge to visualize. Frankenstein "selected his features as beautiful," so I tried to draw his face with normal human proportions (perhaps his jaw is a bit less deep than it ought to be). The result doesn't give nearly as big and boxy an aspect as I'm used to seeing him drawn with. Also, I understand him as basically looking like an anatomy chart with skin shrivelled so tight that it doesn't properly conceal the tissues underneath. In my first attempt, I thought I delineated the neck muscles too clearly, as if he had no skin at all there; this version, by contrast, almost looks normal. Perhaps it's not possible to do justice to the fine detail that really makes Adam as disturbing as he's supposed to be, with just a pencil at this scale. I ought to do a closer-up drawing of just his face at some point.
Dracula is much easier to draw. He's given a very detailed and clear description, and, although he has inhuman features like pointed ears, his overall impression is that of a normal human, which is ironic because he's not one at all, whereas Adam is. So there isn't the issue of trying to capture anything subtle or truly unusual.
