I absolutely love Miya Cech, I follow her on insta and she seems adorable. But I doubt this is the right track to follow for a character like Toph. (I'm also certain this wasn't Miya's decision but rather the writers, but they are once again letting the young actors take the fall for them just like they did with the changes in Sokka's character, I'm noticing a bad pattern here.)
The whole point of Toph is that she was raised with femininity and grace forced upon her, manners and etiquette being an important part of high society. Being feminine for her also meant not being able to fully embrace her element, seeing as earth is often associated with brute force and strength.
Being feminine just wasn't her, and in running away and embracing who she really is she rejected it completely, learning to love herself in her own way. Toph being Toph drove forward the story! And yes, this came with a bunch of flaws. Toph had a big mouth, was aggressive, rude (which she chose to be), not hygienic, and chose to exhibit bad manners.
I once again notice this pattern of the Netflix writers taking any flaws a character might have and trying their damnest to erase them. Katara wasn't allowed to be a thief, or decisive, or angry. Sokka wasn't allowed his sexist -> feminist arc. Aang wasn't allowed to actually run away from responsibilities. And now Toph isn't allowed to be the brutish girl she is.
