Adding Light to eyes

My digi stamps have a lot of black in them, so they need some shine. All I do is color the entire iris black, then make a small outline around the edge with whatever color I want them and then just put a white dot on the top and two small on the bottom. I have used a white gel pen that works the best, but have also used glaxy markers, and martha Stewart Opaque markers. Someimtes I don't put the small dots on the bottoms.
