>>8129726Do you have a disorder that makes you think people's faces are round?
But to answer your question, artists usually use themselves as reference and Jr has a pretty square face.
All artists have various hang ups in their art, including sculptors who make our toys. So they can be pretty easy to spot if you're familiar with a toyline, despite their names rarely/never appearing.
Also, i hate Chris Sprouse. I can live with Jr's females looking like manly trannies, but his style is worse than a Frank.
