Ok so the next rig was to animate the arm again (though this time its upright, like a human arm). Based on the videos I watched previously, I went for more of a human look to the rig.
My first, not so good, attempt of an arm.
Alec demonstrated this arm movement to me in 3D Dojo- yes I need all the help I can get.
I really like the anticipation I achieved in this arm movement, and the follow through from the claw.
Forceful arm motion- I think it needs more follow through at the end.
