Though come to think of it, if you decide to modify these races in any way as is routinely done with elves and orcs, would people perceive that as cultural appropriation?
When I brought up the idea of Ethnically, and Culturally diverse fantasy races.(i.e. Elves would have multiple civilizations, and diverse looks so that, much like Human, a Liosaelfa, a Mannegishi, and a Quinametzin, while all Elves, are as different as a Viking, a Cree Indian, and an Aztec. I was accused of everything from cultural appropriation to colonialism.
