It would be nice to see a tutorial using the methods decribed by Jason Osipa in his book "Stop Staring".
The Stop Staring book is great but it would be cool to have a video instruction of the same methods since a lot of people find learning by video to be more intuitive.
The tutorial could cover modeling a nicely designed cartoony head like his hero character "Miscy". Then you could follow on with creation of the emotion morph targets and his custom gui for animating lip sync.
Or just a modeling tutorial of a nicely designed appealing Pixar style cartoony guy (Like Mr Incredible, Syndrome) with nice animatable disney style eyes and mouth.
Maybe you could get this Andrew Hickenbottom guy to do a tutorial. His Playboy Bunny character is great and he is in the UK.
