Forget paint. Use
gimp if you have nothing else.
You don't make a circle for the head though, the circle is the sphere in the end. You make a square 128x128 pixel image that gets mapped to the sphere. There is some bending, so you have to account for that when you make your textures.
It is a little bit hard, but just play around with a solid color backround and some face parts... eyes, mouth, etc... You'll get the hang of it.
Then
preview them mapped to a globe using gimp... if it's good, make an auction for it!
(btw, I'm just using the search button to find all of this stuff, I recommend you do the same for anything you need)
