I like hand-drawn portraits in games where there aren’t detailed character models, but in a game like BG3 I prefer to just see the “actual” in-game faces and apparel of the characters. That said, I’d like it if we could have different angles, distances and backgrounds, and possibly even expressions, for our character portraits like DA:O (though I seem to recall the facial expressions available for that ranged from neutral to terrifying rictus). Not a priority for me, though.
