I never said it was constructive. But his comment is true, whether you like it or not. If you find it childish, so be it. But you were childish right back, so I don't really think you have a place to complain about it.
I don't really care whether you "open your eyes" and all that you said... I don't peruse DA enough to see art like yours and complain about it. I have the magical gift to ignore all the wish fulfillment artwork that has plagued this site.
What I am trying to say is that if you can't handle negative feedback, either disable comments on your artwork or stop posting it online. Because if you really were capable of acting more mature than a 13-year-old, you wouldn't whine like this when someone comes along and points out the flaws in your picture.
A respectable artist would have replied, "I disagree, but thanks for the feedback."
You, on the other hand, continue whining and fighting like ~
DJ-Anarchy (or anyone, for that matter) has no right to say something other than, "lol, that's hot."
So, I reiterate my point: Grow up or don't post your art online.
Oh, and "haters" have valid opinions too. Just to point it out.
