Well I'd say it looks like her, though I don't have any frame of reference.
On to the Crits:
Your AA makes her face look blurry, on the left side, and blurry and still not smooth on the right.
I think she needs more contrast, and her hair looks over dithered when compared to the rest of her.
So to recap:
*More contrast
*Less blurry AA (less AA colours, with more contrast between shades.)
*More shades in the Dither pattern, or forgo it.
*Also might want to AA her shoulder and hair.
Heh, recap was longer than the piece it was recapping...
