Man, this rigging thing is a bit hard!
I've spent the last couple of weeks doing and redoing and redoing the rig. Its a damn heavy slog to start with but is worth it in the end.
It must take months and years of practice to get exactly what you want.
Anyways, I've got the rig at a 'usable' stage ready for some animations.
As a tribute to the world cup starting soon one of my animations will be kicking a ball and maybe saving a shot too
Anyways here's a pic of my current rig (definately will change) and a quick pose (as I'm testing for deformation problems etc).
