I have just sought pictures of the villain of Mulan, and well, is asiatic and he have a falcon... he s a Hun... Are you talking about Shan yu ? I Because in the pictures I see he really don't look like thias Nomad hunter.
for info there is so many things about hunters withs eagles on the web like here[link] personnaly I see and read so many things like Animan or National Geographics where you can find plenty of gorgeous things about traditionnals clothes.
don't worry about it. like dogmaniac said, shan yu is an iconic character that people are used to (darned disney, lol). he just has a similar facial structure and he's got a hood and is carrying a bird. eagles are much more awesome than hawks. and i love your oc.
