If you're an artist, this text wall is worth your time, I promise.
So, imagine your shower breaks, and it's something in the plumbing. That it's a pipe somewhere in the wall that needs to be ripped out and replaced. You get a plumber to come and fix it, and when you pay him and he leaves, your bathroom is trashed, there's a hole in the wall, and your shower still doesn't work. You would say that this person is a bad plumber, yes?
Why can't you tell someone they're bad at art or not an artist?
I've never understood this. Take two examples. Etsy and deviantart. On Etsy, you're not allowed to say anything negative about anyone's work ever. Even if it's terrible. You can buy a paper lantern at the store for twenty dollars, put it up as hand made lighting, and sell it for 80 or however many dollars, and you can't say jack.
Both of those examples have used money though. On dA, excluding prints, art isn't put up for money. You post art because you want to post art. Also not counting commissions. Just, art. If someone publicly posts their art, is it wrong of you to say, "Your lines on shaky. You might want to work on your shading and lay off the photoshop effects?" Is it wrong to say something isn't art when it's the 28th in a 50 piece series of crotch shots? The first in the series?
Consider this, for a moment. I've always been told, all through school, by jaded art teachers, that art is everywhere and everything is art. 7 art classes later, I support one half of this theory. Art is everywhere. In truth, just about anything can be art.
But everything definitely is not art.
Even if you draw it. Even if you paint it. Even if you dodge and burn and lens flare it. Even if that 28th flaccid penis is posed so artfully. And don't mistake that for me saying that nudity = not art. I'm referring to the overwhelming amount of straight up porn that makes it on to dA.
In addition to this, I also believe that, no, not everyone can be an artist. You need creativity, which a lot of people have, yeah, but you also need skill which a lot of people do not have and do not have the patience and discipline to get.
Don't mistake this as an I'm-such-a-good-artist-give-me-your-love-now post. I personally find myself decent with a hell of a lot of room to improve. I post this because an acquaintance of mine recently entered an online art contest and posted it all over facebook to get her friends to like it so she can get 1000 dollars for college or something. There isn't a lot of good stuff in it, but the amount of utter crap her entry was plus the fact that it has sixty something freaking likes while most have two just makes me rage.
