weird looking dragon with hair.
Careful your lack of acceptance for non Western culture is showing, and its not a good look on you
Dragons from outside European cultures tend to have fur and scales just like Shisu, the world is big and cultures evolve over time with some parallels. This can be seen in the many variants of what people consider dragons.
These images all show Eastern dragons from varying regions, but one similarity they all share is its head being covered in fur or even having a main much like Sisu who was inspired by these dragons. Furthermore Sisu, like the dragons above, has scales on her body after all the fur. They are very smooth and takes the Mushu/Maleficent approach of scales of not really showing their scales but being simplistic designs.
By saying a dragon looks weird with hair you're diminishing the culture and mythology of countless of countries just because she doesn't fit your image of dragons, which lean towards a Western stereotype.
There are plenty of dainty princess movies. There's no reason why female leaders can't also be warriors (cf. Joan of Arc, Boudicca) such as Merida, Moana, Mulan, and now, Raya.
To add to that there plenty of female leaders being warriors from Southeast Asia:
Lady Triệu was the leader of a Vietnamese rebellion against China in a fight for their freedom from the empire.
It is said that she is famous for saying "I'd like to ride storms, kill orcas in the open sea, drive out the aggressors, reconquer the country, undo the ties of serfdom, and never bend my back to be the concubine of whatever man". She is highly celebrated and regarded in Vietnam for what she has done in the country, now acting to many as a historic folk hero on par with people such as George Washington and Simon Bolivar.
Walinong Sari was a princess from the modern day region of Malaysia who not only was famous for her beauty, but also known for being an expert in weaponry like Kris, spears and swords, and her mastery of silat, the Malay martial art. She is now considered a folk hero, and honestly I wouldn't be surprised if Disney pulled some inspiration from her traits for Raya who fits that description to a Tm but is just from Kumandra.
I won't be listing more but there are plenty of examples of women being warriors and even princesses from the region that inspired Raya and the Last Dragon which just goes to show you not every princess has to be in a ballgown singing with her funny sidekicks. If Disney were to do that more often people would likely get bored of having the ballgown princesses everywhere.
