Toon shader setting

[Marmalade Boy]

Hi gang,

I've been playing around with the toon shader but I am unable to get more internal lines to show. does anyone know hot to get more internal lines to show up? I've messed about with the contour angle and contour width but i am not getting the results I want.  I try importing from Maya with lots of hard edges to the short but still nothing. I would like the shirt to be super wrinkle without adding more geometry/modeling. In the second image, I would like to hove more internal line definition in the chest and  arms. Any suggestions?

Thanks in advance.
