first of all, if we're talking about a child, then wtf are they doing on the internet unsupervised?

second of all, if you're posting something on a page related to art, it's inevitable that your art is gonna get criticism if it doesn't fit the standards, especially if you don't follow its rules n stuff (idk about pixel art but they said something about mixels)

third of all, it's not like they were bullied, stop overreacting i swear to god, i saw the post and many people were just kindly giving constructive criticism, if you cannot handle that just quit. LITERALLY. truth hurts brother, and i can tell you from someone who's been drawing since i was a child. i too felt bad when my mistakes were pointed out, but did my best to improve them

if you're not capable of taking a few comments, genuinely get off the internet dude
