Maya - IK/FK and Catching and Throwing

I enjoyed creating the catch/throw because it was a good learning experience. It helped me improve a lot more when two objects collide, and after a while I came up with this. The problem is the speed of the animation, as it seems robotic still.

The pushing of the block was frustrating because I had spent 2 hours on an animation which crashed, so I had to restart. But in the end, I'm proud with the IK/FK usage, however the walking could be improved.
