3D constraints

For this 3D exercise I animated a girl rig picking up a box, using constraints and setting up the parent in order for the box to attatch to the character, so that the box can be lifted. I found this exericse hard as the constraints key frames were not saving in the right places, however I managed to fix this problem with some help, cause constraints are confusing. 

In regards to the animation itself I think that the action could be a lot smoother, especially when she bends down as the body doesn't move at the same time.
