incorrect leg anatomy
“Missing or reversed joints and other such anatomical errors. Applicable regardless of degree of anthropomorphisation - both horses and humans have same amount of joints in the limbs. For humanoid legs on otherwise quadruped characters, use semi-anthro instead (and don’t forget to remove pony if it refers to same character)”
P.S. “Humanoid legs” as in, hindlegs with distinct shin (between ankle and knee) area since horses have that obscured by muscles.
Technically “human shoulders” aka humanoid foreleg structure should count too, but usually it’s done for ability to move forelegs like ponies in the show do, and often does not have corresponding hindleg humanoidization, and hence I think is fine as “pony,human shoulders”.
