You've got some amazing amounts of detail in this one. O.o

Her eyes have this calculating look, especially since her smile seems to carry to her eyes as well. She reminds me a little of me when I'm in a certain mindset/mode.

Her neck creeps me out. That's what holds the creepy factor for me in this pic!

My favorite bit might be the detail, light and coloring on the chain. On my screen at least, it's photo-realistic. ^_^

I do love her eyes too and the way her smile touches them.
