What are some characteristics of the aztecs?

In terms of appearance, most Aztecs were rather stocky, or lean, and a medium height, ranging from 5 feet to 5'9. Their hair was thin and straight, occasionally some would wear beards and mustaches but they'd remain short. Their eyes were an almond shape and wide, and their nose was pointed, or an eagle shape, if not their facial features were nearly completely altered due to face piercings.
