Great, something you need to know though:

Play around with turning the IK ON and OFF for the feet and hands (try different combinations and see how the balancing responds as you drag the figure.  I just want to emphasise the "Drag" part as well, because you need to "Drag-Pose" the figures body parts using the translate tool, don't use the dials.

I think you're in for quite a pleasant surprise if you do it right!
