Did you see the personality and the VA they gave her? No way the old badass look could merge well with what we have now.
I disagree; you can be a lovely person with a larger-than-life full of joy voice even if you have gone through massive trauma and scarring.
Regardless of what you think about the features and voice actresses, the pristine, almost plasticky skin on her face doesn't match the rest of her body or the story. Either she, as a an Avernus firebomb barbarian, had total immunity to fire and acids (and then her body should not have all those burns from scarring), or she did not (and her face sustained the same damage as her horn, neck and upper torso). It is a big detail that makes you go ????? and breaks immersion, by bringing meta considerations like the perceived attractiveness to the target audience, and the princess classic trope "beauty is never marred" to the forefront of a game known for its commitment to action-consequence and gorey grit.
Maybe there is an in-game story reason for that baby-skin face, and maybe Astarion has a couple of lines asking for beauty tips for his crows-feet, but right now it seems like a marketing decision, not a story-driven one.
