My first 3D character RIG

Here is a snap of my first rig for my 3d boy character. It has been long working on it. I had some issues in defining proper deformations. At one point I was stuck in doing that as max6 gizmos to do that does not work perfectly, but I have found out the way from cgtalk, so will be finishing it soon. This is really a basic rig, with lip bones and a jaw bone.
