calling arty people!

I've had a craft idea that, for once, I'm having trouble actually utting into action. What I want to do is make a small rectangular black velvet bag, a bit bigger than a CD case. It will have a zip across the top and a black cord shoulder-strap. I then want to applique a design on it in white felt. What I want is to have the image of a face, as if looking out of the shadows. You know when you get those very gothy photos of people all in stark black-and-white, so you have just black and then only the lit portions of their face visible? That's what I want. Probably quite a rounded, childlike face, head turned down and to one side. I'll cut the white portions out of felt (needs to be very simple lines) and the black velvet backing will represent the shadows.

I'm having great trouble designing this. If anyone is any good at this sort of thing and could come up with something, either by drawing it or finding me a photo I can work from, they could have a bag like that as repayment :)
