Here she is from the Good Genes Challenge. There you can see all of whom she gets her genetics from. There is no Bella in her, but meetme2theriver pointed out that Tara is also based on the face 2 template, so that would explain some of the resemblance. However, there is something up with Tara's face in that it doesn't age, so Beatrice's features that she gets from Tara won't age either. But she's got elf ears, so that's not exactly out of place.
