This is a little character I created for my upcoming free animation tutorials. It has a complete rig with arms and legs with Both IK and FK. The face has all the controls needed to be very emotive and I think its also good enough for basic lip synch.
You can use this model & rig to practice animation, it is really user friendly, very simple yet powerful rig.
You have to credit me if you use it in one of your animation, demo, or commercial project. Anything you guys do with it, I would be really happy if you send me a link to what you've done with it so I can see :)
Happy Blending :)
