Arm Controls

Start by making a curve and snapping the centre point of it to the wrist, i then selected the control and the ik handle and then constrained these points. After this i selected the control and then wrist joint and oriented them.

I then created a cube and snapped it to the shoulder joint. Then selecting the control and the shoulder ik they are point constrained meaning they move around that point. I then parented this control to the central spine collar joint.
