Please, for the sake of all artist's communities worldwide and for the sake of art in itself, don't ever let yourself turn into this. Don't let the number of pageviews you have here make you think that you don't need to get any better at what you do, because you always need to work on getting better. Just because you manage to sell some of your art, don't stop and say, "This is good enough", because you can do better, and then you can sell better. But most of all, don't fall into the pit of so many self-proclaimed art gods and goddesses thinking you're popular because your work is good, when really it's because it's based off a popular anime that's been bastardized six ways from Sunday by so many idiot fantards, and those same fantards will eat up anything based on that anime no matter how crappy it looks. Don't ever forget that you are an artist, not a fanart whore.

And when someone goes out of their way despite all fears and convictions to hand you a bit of helpful critique, either thank them for it or don't say a damn thing. Sending people to attack them because you took it as a personal attack just tells them and everyone else who has a lick of sense on this site that you're too stuck up for your own good. It's better to be silent and thought a snob than to open the reply box and remove all doubt.
