I meant South Asian, I am South-East Asian, pure bred and grown in SEA, so I know for a fact his face is not SEA at all, not even Burmese or even Shan, they have fairer skin and those who have Ralf-skin tone, don't have a facial feature like him.
That is a South Asian face, maybe southern India, I am not very sure, but definitely not SEA.
That being said, I do agree that the fashion choice could be better, but Ralf fashion work for his characterization as well since Asian students are dictated to be submissive, which is Ralf, and his whole story arc was you choosing whether to encourage him lead (Confidence path) or be the leader for him (introspection path)
