Aside from art, how do you explain them to your players? Are they well-versed in Asian mythology?It's a man with an extra eye in their forehead. It's classic Asian mythology People have eyes.
Anyways that's what art is for.
What I'm getting at is that these days most D&D players are fairly casual, and don't spend hours studying rulebooks. When they choose a species, they are generally basing their idea of that species on pop culture stuff picked up outside of D&D. So cat people are popular because most people know what a cat is like, and so on. If the player can't get a clear idea of what a species is like based on prior knowledge, they are unlikely to choose that option.
