I dunno if there's already a stamp like this, but ya know, I've seen pretty good art that lacked proper anatomy, but I've also seen art with bad anatomy that made me want to stab a fucking baby. So, no, you don't HAVE to learn to be your best, just take time on your art, but you can at least try to learn, because learning anatomy won't hurt your art. Not learning just isn't helping you improve. And if you don't bother to learn, please don't say "it's my style." Bad anatomy is not a style. If it is physically impossible for the thing you drew to move properly, then it's bad anatomy.
I hope this stamp is of use to people. :3
