Gotta agree with Alexsani. Overall nothing much has changed to correct the direction of the lightsource, making her dress look about the same as it was 5 years ago, unfortunately.
However in Alex's edit, I think it could have been handled better.
To correctly handle this, think of the dress as a cone and set up the lighting from there. Work from the general to the specific, so folds would come later.
There are also some faults with anatomy. While there is a difference between what were essentially tubes for limbs you had back in '06 and the more-defined segments of today, in both versions she seems to display an odd juxtaposition of stiffness and grace (particularly her arms). There's also a lack of balance, like you went directly to drawing before thinking about it. Mirroring the drawing horizontally, as I find it, makes these problems easier to spot.
Edit, maybe.
