For that confession, that was the way to do it. I don't know who posted it, or who the artist is, but that blog is meant for stuff like that. To be honest it only looks like a simple simple drawing with tons of photoshop. It would most likely look horrible without all the photoshop and such. And it really doesn't matter if she's young. Tons of artists are young. She has to learn to deal with it. She will get tons of hate in the future even if she does get better.
They basically said her art wasn’t art, so I really don’t think they went about it the right way.
