Trouble with painting eyes

I want to share the method I did for painting eyes, pupils and eyebrows.
First, I started painting the eyes and teeth with corrector ink brush, the leftover areas were cleaned with a used very thin pen (something sharp and small works too, like a wood stick)

For the eyebrows and pupils I used the same used very thin pen, note the pen no longer had ink in it, so I used acrylic black paint.

Done! I have to clean some areas but it looks very good now.
