I was reading this thread last night and i was actually shocked about some of the things that you said and i just want to give my two cents.
You claim that you are an artist and have some talent in the area, which i serious don't doubt and i personally have no ability to judge in this area because i have no skill in drawing at all. But i would hope that it would be someone like you who encourages this girl and inspires her to improve. By all means i am not saying you should lie, but you don't have to be nasty to be honest. But constructive criticism is what the art world is all about, you as someone who has a superior knowledge of the subject SHOULD have been honest, but have been nice at the same time. What have you done by insulting her and her drawings? Do you really think that you are helping her by being a jerk? Do you think this will help her improve and inspire her to better herself?
No, all you have done is hurt her and weakened her resolve to be an artist.
And how can you say she should give up on her dream because she has no skill, skill in a thing like art isn't hereditary, you aren't born an amazing artist. You have to learn and improve. I am certain that at one point in your life you wasn't the big hot-shot snobby artist that confronts people online by belittling them and there work, but someone just like this girl, trying to improve because she wants to express herself through art.
:flaw: Shame on you!!
Two cents.
