Quit harassing children and new artists. Do you people really, honestly think all amazing artists just burst forth from the womb with polished skills and a deep understanding of the intricacies of anatomy and colour theory?
No, don’t be ridiculous, let artists develop and grow. Either encourage them or leave them alone. It’s not “okay” just because they’re not a kid, people can start drawing at three or thirty, let them be. With effort and studying, even a late-start artist can improve impressively, so just… don’t tear people down for posting naive or weird art and being proud of it.
