I’m sure I didn’t INVENT this, but this is definitely the first time I’ve done it.
A caricature is a representation in which the subject’s distinctive features or peculiarities are deliberately exaggerated to produce a comic or grotesque effect.
Typcially you see it as a real person reduced to something more detailed and exaggerated than a comic-strip character, but certainly less realistic than a photo.
A reverse caricature, per my own definition, is when you take a cartoon character, assume you know what the REAL person from which those features were oversimplified looks like, and strike some middle ground.
Then again, you could argue that this is just a more detailed cartoon than I usually draw. (And you probably will, you big meanie.)
