As a suggestion for all those who are intersted please search for joint animation in after effects. It is the most easy and perfect method to animate any character close to human feel.
In that technique you need to make your character (2D) to have joints like human i.e ball joint, rotating joint etc (I am nill in biology).
I like your umpire; it's a good model.
