Like, everybody is kids, and she is a kid too. Maybe she could've been in Gen I if Gamefreak would've bothered to put a girl option.
As for Leaf, she is not bad, but she felt like "hey, you can pick this girl if you like. She's the female choice."
The model is fine, the outfit is fine, but her presence in Kanto was out of place. If anything, I like to think Leaf is actually Green, just grown up.
I mean, comparing sprites, FireRed looks like an older version of Red.
