Looking at her pictures from her teenage years, I can see how much she's changed. I think her features actually changed a bit. When she was a teenager she was less squinty, her face was smaller, her skin was fresher and she just had an overall happier feel to her. Now, in her early twenties, Charlotte looks like she's already seen and experienced enough of the world. Yes, we do see her smiling and jubilant from time to time, but it's a lot rarer. Charlotte is still beautiful, but I think in a lot of ways she just cares less now, she'll wear plainer clothes and not do her hair up so much anymore, etc... It's not necessarily a bad thing for her to not care about dressing up anymore, but it kind of shows how much she's changed and grown up over the years.
