Aside from the whole girlification thing (off the shoulder sparkly dress, smoother hair...) I have a different objection. This is a terrible piece of artwork and I can't believe that it was commissioned by Disney, the home of amazing artists. Her torso is too tiny, her shoulders look dislocated, and the whole hands-behind-the-back pose always strikes me as either insecurity about drawing hands, or laziness. I am hoping that this is just some kind of rough draft that made its way onto the internet... I never want to be the mean critic type person, but I just don't want to believe that this is a completed design.
I hope maybe they stick with the other drawing in this thread, the one that's a more three-quarter view. It looks more proportionate, and sassier, and at least she's not completely hiding her hands.
