First of all, the serpent woman would like to wish everyone a very happy Halloween.
The one with horns is my first version of the serpent woman. I like to imagine this is how she looks when she's just a young monster.
And the second version is how the serpent looks when she matures. I wish I had done this in color, I'd like to see her as a crimson serpent.
Anyway, happy Halloween, and beware of monsters and ghouls.
