I actually painted them Jeannie. I first selected a very dark color, not entirely black, but close... and made my brush the size of the yellow area (using [ and ] to adjust the size of my brush). I used a feathered edge brush and just clicked over the yellow area to paint it. Then I changed my color to something very light (not straight white), more of an off white/tanish to put the glint in the eyes. Same effect, change the brush color to something small and click where the original glint was (you can usually see it on a glowing eye photo or get a good judgement by the direction of the light). I usually make 2 small dots close to each other for the glint. Its super easy. Now try it and post what you came up with.
I'm not very good with words so I hope I explained this well enough.
