Hmm...
Looking at the other reviews on this piece.. You're a whiny little bitch aren't you? Learn to take criticism, or stop trying to be an artist. You won't get ANYWHERE as an artist if you draw stuff like this and tell the people who give you constructive criticism to fuck off. This is not a great picture. It's average AT BEST.
The anatomy is off, her chest looks wonky, her left arm looks like it disappears below the elbow, her feet look completely messed up, you didn't draw your own background and instead used a real life picture, which just looks awkward, especially considering the limited detail of your drawing, her right hand looks like the bone is trying to break it's way through the wrist with how sharp the curve is, her legs are too long (as Mindraker said before you oh-so-rudely rejected his advice)... On the plus side, I really like the way her face and hair looks, and your art style, though simplistic, is pleasing to the eyes.
Ignoring the flaws in the picture itself, I don't understand you. At all. I looked at some of your other art, as well as the reviews, and you seem to be a perfectly reasonable person in every one of them. But when it comes to this picture, you act like a spoiled child that deserves nothing but praise, and everything else you damn well please. Why is that, exactly..?
