Read a couple of those posts and not one of them mentioned Mazzy!
Come on people, she's da bomb! The slightly arched eyebrow, full lips, and near-perfect facial proportions compared to the rest (Imoen scarred, Jaheira and Viconia seem to have got their inspiration from Picasso, etc.) and she's got a rad do!
I don't know who the portrait artist(s) were, but the positioning of the eyes especially on Aerie and Jaheira are horrible. Cock your head to the left when you look at Jaheira, her right eye is a 1/2 inch (proportionately) closer to her nose, as well as being noticeably higher than the left eye on the face. Aerie's ears are lopsided, and she looks malnourished.
I say, go for Viconia, it works well as a plot point no matter your alignment, since Neutral Evil isn't terrible (Evil cavorts with evil, good sees the possibility of redemption) for your romance, but pine for Mazzy!!!
