CA use Mongolian music and vocal to represent Huns, but it is okay that Huns is Mongolian ancestor.(Han dynasty vs. Huns on Mongolia grasslands, after Han dynasty won the campaign that killed Huns' Khan, Huns was divided two groups: 1. Southern Huns (made obeisance to the Han dynasty) 2. Northern Huns: escaped to central Asia, finally, they migrated to Europe and destroyed Western Rome empire.
Attila Portrait really need to fix. Maybe it because Southeast Asian are all over the world, Western people don't know North Asian(north of Yangtze River) looks like, some of them think all of Asian looks same

Attila is North Asian, not Southeast Asian like second picture. He has a big nose hole + a flat nose + a big-prominent forehead...................
North Asian are high nose(lower than European) + normal nose hole(adapt to the cold).
Southeast Asian big nose hole() + a flat nose(adapt to the hot, tropical)
Those are common sense.
