sorry for the delay in responding guys, been a bit busy over here.

I've got a problem with the rig I'm learning on and am probably going to have to redo it (good learning experience though).
Also its not easy finding reference video of the type of punch I'm after and if you dont have a video camera to capture it then it could get difficult.
As with what priimate is doing, I'm going back to try some 2D studies on the main parts of the animation and am going to have a go with 'plastic animation paper', a shareware program for creating 2D animations with a graphics tablet.
