She does have less pronounced even features than her BG I+II portraits. Though as a half-elf it isn't really a problem, though it does show that Larian's art direction is divergent from BG II in terms of fidelity to legacy characters. Really, what bothers me is that they really whitened her skin, particularly if they are going off of her BG II portrait (which seems to be what they are using for BG II) Jaheria was really not white in BG I-II so it's rather...jarring to say the least.

She and her husband were from Thethyr/Calimshan IIRC, which is sorta the equivalent of Iberia & Morocco in Toril.
