Cell Shaded Cartoon Bull

I have been playing around with using Cell Shading lately which gives your models a cartoon look.
To experiment I have used my Bull that I modelled as part of the Canimation project.

I was quite please with the effects that I managed to produce, what do you think?

I think the bull looks quite mean, and the cell shader, adds more emphasis on the muscle contours.

And another view showing the back of the bull.
