I can't really answer this because I don't have any background information about Amira but I can tell you about the young girls in your country.
Ages of the girls and their personalities in America are like this.
0-5 : Pretty much kids. Cheerful-ish.
6-9 : Good children... they are pretty close to their parents.
10-17 : Yeah... spoiled children... they are spending all their time on social media and it's ruining their lives
18 - 29 : Adult but they still vibe and have good friends in college.
30 - 40 : Adults and they are mature
41 - dead (I'm so sorry) : Good people... wholesome :D
Ages of the girls and their personalities in other countries are like this
0-5 : either very smart and already learning a lot or they can't afford to have education.
6-9 : smart... they are probably starting to get very competitive and enter competitions. If they can't afford it they are working very hard.
10-17 : VERY smart. They are already planning their future. Or.. if they live in a poorer country, they will still work very hard to help out their parents.
18 - 29 : Already have a life, studying in college. And if they couldn't afford it since they were little, they would probably be working hard still... maybe getting social to find someone.
30 - 40 : If you were successful when you were a kid you are already pretty / very successful... and once again, if you couldn't afford education when you were little, you probably already have a kid or you don't have pairing at all.
41 - dead (Wow I shouldn't be saying this) : Either very / pretty successful and teaching your child and grandchildren how you lived. And if you couldn't afford it... you might be working hard until you... OMG I hate m y s e l f for this I'm so sorry.
But yeah, if Amira's traits are similar to these then you can write that.
To talk about the difference, just state what Amira is like and what the age of a girl in your country.
