So, writing advice is needed. How do I describe a maori person?

Saying directly, "He is a maori" sounds clunky, and I've been told that describing someone's skin as "brown", "savage", "wide-eyed" etc. that I have seen in a lot of books (cough cough FanFictions) is apparently not good writing.

I've watched a million videos on what not to do but not a single one has told me what to do.

I want my writing not to suck. Please and thank you.
