Your drawing and colors are really exceptional. Your stuff always looks great and this does as well. Still, I always feel a little weird pointing out things to someone so much more talented than myself... Krasch is right about spine thing, in fact, Wonder Woman's pose is rather awkward overall and shattering parts and ripping clothes aren't following physics or lending to the sense of impact. In spite of these things, it's still a pretty stunning piece. Good job.
The colours are really good, only shame is Diana is now dead from having her back snapped in two. Her lower body is almost vertical and her top half almost bent back on it.
