Oh! now this one is pretty nice! I like her expression, its a lot like Martha Stewart- which isn't a bad thing in my opinion, but a strong point- it attributes a lot of character to her. It is nice how the body transitions into the spider form too.
Beautiful ^__^ Someone mentioned earlier that she is reminiscent of one of the mythological gods. I believe the Hopi Indian tribe had a Goddess "Spider Woman" named Kokyanwuhti (I had to look that name up XD)
She is certainly what I would imagine a spider goddess looking like.
