In Tibetan art Kirtimukha devours vegetation that sticks out of his large mouth and may also have strings of jewels or three round jewels in it, as above. His horns are like sprigs. The symbol on his head represents a crescent moon, a sun disc and the dissolving point of the primordial sound (nada in sanskrit).
In sculpture he often holds a snake and has a beak like a garuda, which is confusing, especially when featured on a small scale work such as the front leaf of a crown.

On Nepalese and Nepalese-style back plates, viyalas or sharabhas are usually between the lions and the makaras and have a human figure half crouching on their back. Sharabhas have the head of a goat, the horns of a ram or a mountain goat, the mane of a lion, and the body and legs of a (rearing) horse, usually with the claws of an eagle.
Viyalas may be half-lion half-horse, in which case they stand on their hind legs. On this back plate each viyala stands on an elephant and looks at a bodhisattva. Above them, a makara, and at the top, a garuda.
