Completed Mystery Box sequence

My completed, edited scene of the Mystery Box Project.

I have edited this to the best of my abilities, however I do feel this could be made much better.
I am not happy with the pixel edges around the box, however after many failed attempts I was still not able to remove this. Perhaps after much more research, and practise I would have found a solution to this. I also wanted to add a glow effect to the box, but was not sure how to achieve the look I wanted. But with experimentation, I was able to get the effect (despite not perfected) for the lambs, seen in my animatic. Also, instead of the light/ glow effect, I experimented and found a different effect, despite not being what I originally wanted, I think its strange and effective.
Overall the animation itself is not perfect, and the walk cycle failed as I was unable to balance my model (I believe I made her shoes to heavy and thick that the pins failed to keep stable inside them. As mentioned before, I had to use a sponge underneath her to keep her standing. Which luckily, after much researching I was able to find away to edit it out, but during the shoot, it made the leg movement very limited hence unable to create the movement and illusion of a walk. Her reaction also is rather fast, I which during shooting I had took several shots of the same shot to slower the head turns. It may have been good practise to print my story board animatic shots to use for reference. Instead of just viewing the animatic every few shots on video.
