May you please explain this? How on fucking earth was your criticism constructive all you said was essentially "you drew this poorly" other comments literally did exactly what constructive criticism is, criticism that says what can be improved upon. I wish I didn't even get ropes in this, as your previous activity even in this specific subreddit makes vou sound like a ultra-asshole. So for your "mentally debilitated child" mind, don't be a dick in your criticism.
How do you use the TF2 ‘Tiny head’ copypasta ?
Every time someone says “Tiny <something>” in response to an artwork, that’s when you copy paste the meme as a reponse.
Alternatively you can simply use it whenever someone makes a short nonconstructive criticism towards another person’s art.
