I don't know what to think ...
Let's see:
*Fleur is a Veela, and she is married with Bill, which surely was rather handsome, so the babies girlies will be pretty red-headed Veelas ('cause red-headed genes are dominant)
*Hermione is rather pretty, even if we don't take into account Emma's beauty, and Ron is not handsome, but he has ... some special fetures, I don't know, I like him anyway, and ... just look at my avi! He was so lovely when kid! I think they have to be: Rose, red-headed and bushy hair, and Hugo, brown-headed and straight hair ...
*Ginny I think is the most beautiful of the Weasley family, more even than Bonnie Wright, and Harry is definitely handsome ... green eyes and red hair! Lovely! They could be: James, brown hair, brown eyes, Ginny's features; Albus, well, like Harry, like JK says, green eyes, black hair, James' features; Lily, red hair, brown eyes, and it could be a mix of both features ... perfect trio!
*Tonks and Lupin ... Lupin surely was kind of pretty, and Tonks had a heart-shaped face, which is lovely ... I don't think Teddy could be a werewolf, because ... I don't know, I'm pretty sure he is not. So, a lil' Remus with multicoloured hair ... aww!
*Draco's son ... he is kind of an arrogant beauty, and he surely didn't marry an ugly woman ... so his son, Scorpius (ugh, such a name for a lil' kid!), turned out to be like Draco, like the book says, but he could have ... her mother's eyes, let's say.
*George and Angelina ... Angelina isn't such a beauty girl, nor Fred or George ... they are lovely, but the same as Ron, they aren't the canon of "beautiful". I can't imagine a ... black red-headed boy? No, nothing comes to me now, nor for Percy's sons.
Well, what do you think? All the babies are lovely!! (I love my kind of Hugo ... I'll marry him someday!)
