This is a character from an unpublished book. She's supposed to be atractive and evil, a woman who will seduce and kill you unless you are somehow useful to her. She's probably holding a knife behind her back.
She's supposed to be in her 40s, and this was a bit difficult for me, because she looked either too young or too old ( I had to repaint her face again more than once) and I'm not sure if I finaly got it.
I did it with photoshop CS3 and a Wacom Intuos 4, using just the default brushes. I didn't use any model, so maybe the proportions are not correct. I hope you like it
