Tengus have various forms on the folklore.
Some of them are like Onis with big noses and red skin, others are full crows, some of them have only parts of their bodies like a crow

Tengus are shapeshifters (as the folklore says) explaining the various forms they can have

The one I made doesn't have a beak, but her hands and feet are covered with feathers, having claws and talons.

Additionaly, tengus surnames are formed by the mountain they were born (usually tengus are born and live protecting a mountain / temple)

Also, I searched about their names, it says "Tengu names often feature aa, k, i, and o sounds. They are seldom more than three syllables long, and double syllable names are most common. Female names are more likely to contain b, m and uu sounds."
