OK, listen up, morons of deviantART. (No, I ain't referring to you, hopefully. I'm referring to the 'tards.)
If you flip out over something as innocent as constructive criticism, then I think you should really leave deviantART. Art is all about improvement, and no-one in the world is perfect.
Is it because you expect instant ass-kissing in the Critique box and comments section? Well, maybe your fanbase (if you're one of those Deviants who have managed to get a decent following), will constantly praise your work, but others will try to give you concrit. Take their words as a compliment as to how to improve your art.
Is it because you think your art is "perfect" from the first try? Please get a reality check, because it probably sucks. (No offence.) Some artists draw multiple pictures of a drawing before they create a finalised version.
I had to learn how to accept criticism when I posted my fanfics on FanFiction.Net. I admit it, I didn't feel proud of myself when I first got concrit, but I learnt to accept it.To be honest, I think you have to learn how to take concrit for the internet itself, and life in general. If you can't accept criticism on dA, then I worry about how you would react in the real world...Also, in b4 accusations of me not even drawing that often, and posting MikuMikuDance screencaps, so I shouldn't be complaining about egotists on dA if I don't even post proper artwork.
I'm more of an art appreciator, anyway.
