I agree that Larian should keep the current heads but add some new ones that look like proper, otherworldly elves (and half-elves). That way they don't have to scrap any of the currently advertised companion designs like Astarion and Shadowheart. At the same time, they'll also please more discerning fans. The more human-like heads I can just pretend are elves with a bit of human ancestry or something.
