Human

A human is a mammal bipetal creature with a similar set of characteristics. They are bipetal creatures with four limbs, two arms ending in hands and two feet, though some may have more. Most have hair growing out of their scalps that can come in every color of the rainbow. Most have two eyes that can come in any color as well.

What is Still Human
A creature must deviate pretty far from the typical set of standards not to be considered human anymore. Just using magic does not make a creature non-human. Having blue skin does not make a creature not human. Even having horns or a tail does not make a creature not classify as a human, though it depends on the degree. Living a long time still counts as human.

What Makes a Creature no Longer Human
A far from normal diet can qualify something to no longer be human. Anything from eating raw meat as a main source of nourishment or no longer having functioning vital signs. A creature who's body deviates enough from the standard is no longer human. For example, a winged man is still a subrace of human, but a creature with wings, a beak and claws is no longer human. Other biological abnormalities, such as the inability to touch wood or the ability to eat fire with out the help of magic makes a creature no longer human.
