Probably because she’s so sickly and cadaverous looking she’s trying to make herself look good by comparison. I can’t see her as ever posing a threat to the likes of Sydney Sweeny, but your mileage may vary.
Sydney has a great body, neck down, butterface!
I can easily see how her features will develop as she ages.
All that said, she’s having a moment in Hollywood right now, so I’m glad for her. I would guess about 97.5% of young actors never do have their “moment” of fame on that level, having talent and skill is only a part of the battle to become a known Brand.
