If your primary and secondary animation were done as a rough drawing, it is now time to put your drawing on model. This means that you have to review your animation and ensure that every single detail is on model and there is no volume distortion. You can do this directly on the original sketch layer or on a new layer.
If your primary and secondary animation was done quite on model, you can proceed directly to the animation clean-up. If not, proceed the same way as you did for the secondary animation task to bring your animation on model.
