Commission I made for , she is a Lillend, here's the description of what a lillend is:
As described in the D&D Monster Manual, the upper body is of an attractive human, while the lower body is of a slender, coiling serpent. The upper torso is usually female, but male Lillends also exist. The lillend also has feathered wings coming from the back, feathers on the end of the tail, and feathers for hair.
The lillend is described as both a lover and protector of music, art, clothing, literature, and all other forms of culture.[3] In addition to being fine at these things themselves, they defend others who create it, and seek out and punish those who despoil it. They can attack by constricting with their tails, and can cast all sorts of spells.[3] They also sometimes carry weapons. They can also play soothing music on their harps. Being highly civilized, they will not always kill opponents and instead merely try to talk some sense into them.
In addition to being protective of art, lillends also revere untouched nature.[3] They often form alliances with others with the same drive to protect nature.
Lillends speak Celestial, Infernal, Abyssal, and Common.
