An error or mistake made by the artist, usually in the anatomy, but possibly in other elements such as the coloring, composition, perspective, or the character's appearance.
This also includes mistakenly drawing a character with the wrong appearance, such as drawing the wrong eye color.
Do not confuse artistic error with bad anatomy, bad proportions, bad hands, or bad feet, which are for elements that are merely poorly drawn, not outright mistakes. The tag QUALITY can be applied instead if the artist intentionally recreates the disfigured art for comedic effect.
Generally you should comment on the post describing what the error is.
