I think the portraits of the dynasty should be DNA-based. For instance if the King and the Queen get's a child the child should look like his parents. And if like one of the parents is white and the other is arab the child should look like a mixed race.
And also i think there should be alot of portraits like 10x more than there was in CK1.
