Yay for the Azkaban look! A lot of people (me too) forget the "wasted" look...you captured it well.
The eyes are very good in mood and character...but they're a bit big...very big for adult proportions, and as a result they also look too close together. Making them smaller, but keeping the outer edges where they are might be an improvement!
And once again, you're right. The eyes are way too big. I'll try to fix it without ruining the Azkaban effect. The angle of her head gives me headaches just to look at and think of working on it again.
Nice! I like this depiction of her. She's less obviously crazy, but you can see that madness mingled with evil in her eyes. Also, most people tend to show her looking a lot younger than she is, but you've got her age spot on.
