I always think of Astarion as 1/4 Elf, that's how I'm roleplaying him at least
Astarion is a full blooded High Elf but he's also a 200 year old vampire. When it comes to his character design, I think the developers might of had a difficult time figuring out how to combine his elf and vampire side. From what I see, the only elf features he has is his angular type face, his ears and his body shape. As for his vampire side, the only thing he had are his fangs and red eyes. They could have designed him a little better. If I were designing him, I would change his eyes and make them slightly bigger, a little slanted and bigger pupils. That would make him a little more elvish. I would also change his hair color as he is already pale enough.
