Care Bears - Tummy

Hello guys,

I'm going to make some t-shirts that will imitate the body of our lovely care bears! :P

Here's an example of a care bear (for those that don't know them):

I just have a problem.. In the front, I'll to have to "paint" the tummy and the simbol... I just don't know very well how to imitate the tummy effect, with the hair, probably some shadows, etc... Can you guys give me some advice?

Thank you for attention

Here's an better example:

I want something similar to that, but the the white part of the tummy, I would like to have it bigger and with more details, like for the example, the hairs.
