Nice drawing overall, but some little things that need to be fixed.
Her breasts for one are really oddly shaped. And her hand does look like it's placed firmly on the ground.
The face also needs work as well as her feet needing added detail.
I made an edit of your pic, ZxC, to show you what I feel needs to be improved.
Now there's still more things I would have liked to edit on, but I'm pressed for time, so I hope the other issues are taken care of as well.
