A fixed grid-layout, labeled chart usually of one character displaying a multitude of varying expressions. These are almost always one of a few fixed templates, but sometimes an artist will create their own. They often feature jokes in addition to the expression drawing practice. For other depictions of varying expressions outside of this stricter format (unlabeled or unstructured) for instance some character sheets, simply use the expressions tag on its own.
