I forgot about Betty's portrait or I would have checked other too, I picked Josette's original Portrait, Barnabas', 1967 portrait, and Angelique PT.
Even though I didn't like PT that much I loved the portrait and the beginning of the story seemed really spooky with that painting.
While I liked the original painting of Barnabas, I really liked the painting from 1967 better. It was so creepy that while Sam was painting it, Barnabas was draining Maggie and causing her to change. (This painting was also a better likeness as well)
And then of course Josette's portrait was so wonderful, I loved the way it was used in the beginning with her ghost stepping out of it. The way David told people about her ghost and showed them the painting. Then how distressed he was when Barnabas moved it.
It was also a very sad looking picture, didn't Josette look sad?
As to Quentin's portrait, I always thought that the werewolf, being a supernatural creature, wouldn't have aged at all. And because the werewolf hadn't been able to exist except in the painting on a full moon, it (the werewolf) wouldn't have sustained any damage, so no missing eye either. Anyway that's my opinion.
