This Blondie rig has all the features you'd expect from a production level animation rig: A fully featured facial system including blendshapes, hair and tongue controls. IK / FK spine, stretchy IK / FK limbs, breath control and other useful features.
You'll find the rig easy to use and intuitive. The facial controls are found in the Jaw channel box - the eye and brow controls in the look target channel box. The rest of it, what you see is what you get; controls in the control layer, geo in the geo layer.
The rig is textured procedurally, so it will render alright as is, maya software or mental ray - but the uvs are laid out should you wish to custom texture.
