Hey Nance. Some tips for yer. Check this out and see if you like:
For the eye, I made an eyelid shape and used the same gradient as on the face but just reversed the direction.
For the lips, I copied the shape and cut a portion of each lip. Then I did a gradient that used the original lip colour and a darker version of the same colour (only adjust the 'k' or black bar if you're using CMYK). Lay the lip portions over the original lips and just adjust the angle and the gradient positions until the seam (or join) disappears.
Hope thats useful.
