Thanks guys, she was a really nice lady and a great cook. We were actually planning to do a recipe book together, she would cook and I would shoot and do the book's layout but ... O well ...
Anyway about the shot...thanks for the comments and suggestions ... I was also thinking about more DOF and actually did some some shots at f/8 and f/16 but the plastic of the model began to become more obvious so I went back to f/4.
The painted nails ...

that's actually supposed to be blood that my colleague painted on. The red burnt out and became completely white. Maybe I should have PSed it away to a duller color.
Funny thing was that my colleague liked the shot so he had it printed on our new HP Photosmart 8750 in boarderless A3 as a poster for his home.
Thanks again.
Cheers,
Matt
