well, im not sure about the toe rigging, but i have a fw suggestions for your animation. I think its an awesome first start and great job compositing, but i dont feel that the motion is very convincing with the walk.
- make sure there is more of a bonce in the step...when you watch someone walk there is a lot of vertical movement.
- side to side movement...right now the center of balance is right in the middle, it should shift to the foot thats bearing weight.
- on top of the body going up-down-side-side make the head bob the same direction but a few frames later (seperate and overlap)

It looks good so far, but i think if you add these elements it will look loads more convincing.
