Cube Love

Cube Love is an exercise where I was not allowed to do any modelling and work on my animation skills. It was inspired by valentines day coming up and /r/blender january contest. I used hooks from lattice vertices to bones to have the same amount of control over the cube than I had when I was playing with the lattice. I have gone time with this and it is now done but I would like critques, bear in mind this is my 3rd animation.
