Capturing One's Essence

Trying to paint Principe's eyes last night, but I don't seem to be able to get it right. I used black to trace the eyes, but it looked too strong, like he had mascara on or something, so finally I have to wipe it off and paint over them with white paint. It wasn't pretty, I wonder how other people do it. I also realized that if I can't paint the face right, my painting will turn out horrible. So I'm getting very anxious now.

When I finish it, I'll definitely take a picture and post it online. Who knew this would turn out to be so hard?
